Check if a thread belongs to managed thread pool or not in C#
The IsThreadPoolThread property in C# helps determine whether a thread belongs to the managed thread pool. This property returns true if the thread is from the thread pool, and false if it's a manually created thread. Understanding this distinction is important because thread pool threads are managed by the runtime and optimized for short-running tasks, while manually created threads give you more control but require more resources. Syntax Following is the syntax for checking if a thread belongs to the managed thread pool − bool isPoolThread = Thread.CurrentThread.IsThreadPoolThread; Manual Thread vs Thread Pool ...
Read MoreGet the hyperbolic arc-cosine of a floating-point value in C#
To get the hyperbolic arc-cosine of a floating-point value in C#, you use the MathF.Acosh() method for float values or Math.Acosh() method for double values. The hyperbolic arc-cosine function returns the value whose hyperbolic cosine is the specified number. Syntax Following is the syntax for the hyperbolic arc-cosine methods − // For float values public static float Acosh(float x) // For double values public static double Acosh(double x) Parameters x − A number representing a hyperbolic cosine, where x must be greater than or equal to 1. ...
Read MoreHow can we create an exception filter to handle unhandled exceptions in C#nASP.NET WebAPI?
An exception filter in ASP.NET Web API provides a centralized way to handle unhandled exceptions that occur during controller method execution. When a controller method throws any unhandled exception (except HttpResponseException), the exception filter intercepts it and allows you to customize the HTTP response. Exception filters implement the System.Web.Http.Filters.IExceptionFilter interface. The simplest approach is to derive from the ExceptionFilterAttribute class and override the OnException method to define custom exception handling logic. Syntax Following is the basic syntax for creating a custom exception filter − public class CustomExceptionFilter : ExceptionFilterAttribute { public ...
Read MoreConvert the specified Windows file time to an equivalent local time in C#
To convert the specified Windows file time to an equivalent local time in C#, you can use the DateTimeOffset.FromFileTime() method. This method converts a Windows file time (represented as a 64-bit integer) to a DateTimeOffset value that represents the equivalent local time. Windows file time is measured as the number of 100-nanosecond intervals that have elapsed since January 1, 1601 UTC. The FromFileTime method automatically adjusts the result to the local time zone of the system. Syntax Following is the syntax for converting Windows file time to local time − DateTimeOffset localTime = DateTimeOffset.FromFileTime(fileTime); ...
Read MoreGet the angle whose sine is float value argument in C#
To get the angle whose sine is a float value argument in C#, we use the MathF.Asin() method. This method returns the arcsine (inverse sine) of the specified number in radians. The input value must be between -1 and 1, otherwise the method returns NaN (Not a Number). Syntax Following is the syntax for MathF.Asin() method − public static float Asin(float x) Parameters x − A number representing a sine value. Must be between -1 and 1 inclusive. Return Value Returns the arcsine of the specified number in radians. ...
Read MoreHow to do versioning with accept header in C# ASP.NET WebAPI?
The Accept header in HTTP tells the server what file format the client wants the response data in. These formats are commonly called MIME-types (Multipurpose Internet Mail Extensions). In ASP.NET Web API, you can use the Accept header to implement API versioning by including version information as a parameter in the Accept header. This approach allows you to maintain multiple API versions while using the same URL endpoints, routing requests to different controllers based on the version specified in the Accept header. How Accept Header Versioning Works When a client makes a request, it includes an Accept ...
Read MoreHow to do versioning with custom media type in C# ASP.NET WebAPI?
API versioning through custom media types allows clients to specify which version of an API they want to use by including version information in the Accept header. This approach uses vendor-specific media types to route requests to the appropriate controller version based on the requested content type. Custom media types follow a pattern like application/vnd.company.resource.version+format, where the version is embedded within the media type identifier itself. Media Type Versioning Pattern The following media types route to different controller versions − application/vnd.demo.students.v1+json → StudentsV1Controller application/vnd.demo.students.v2+json → StudentsV2Controller Custom Media Type ...
Read MoreGet the HashCode for the current UInt32 instance in C#
The GetHashCode() method in C# returns a hash code for the current UInt32 instance. This hash code is used internally by hash-based collections like Dictionary and HashSet for efficient storage and retrieval operations. For UInt32 values, the hash code is typically the value itself, making it straightforward to understand and predict. Syntax Following is the syntax for getting the hash code of a UInt32 instance − uint value = 100; int hashCode = value.GetHashCode(); Return Value The GetHashCode()
Read MoreHow can we create a LOG filter for Logging purposes in C# ASP.NET WebAPI?
Action filters in C# ASP.NET Web API are used to add extra logic before or after action methods execution. The OnActionExecuting and OnActionExecuted methods allow you to inject custom logic at specific points in the request pipeline, making them perfect for logging purposes. A LOG filter helps track API method calls, execution times, and other diagnostic information. This is particularly useful for debugging, performance monitoring, and audit trails in production applications. Syntax Following is the syntax for creating a custom action filter by inheriting from ActionFilterAttribute − public class LogAttribute : ActionFilterAttribute { ...
Read MoreTimeSpan.FromMinutes() Method in C#
The TimeSpan.FromMinutes() method in C# is used to return a TimeSpan that represents a specified number of minutes, where the specification is accurate to the nearest millisecond. This static method is particularly useful when you need to create time intervals based on minute values. Syntax Following is the syntax for the TimeSpan.FromMinutes() method − public static TimeSpan FromMinutes(double value); Parameters value − A double representing the number of minutes, accurate to the nearest millisecond. Can be positive or negative. Return Value Returns a TimeSpan object that represents ...
