C# Int16 Struct

The Int16 Struct in C# represents a 16-bit signed integer with values ranging from -32,768 to 32,767. It is also commonly known as the short data type and is part of the .NET value types that directly inherit from System.ValueType.

Fields

The Int16 struct provides two important constant fields −

Common Methods

Using Int16.MaxValue and MinValue

Example

using System;

public class Demo {
   public static void Main() {
      short val1 = Int16.MinValue;
      short val2 = Int16.MaxValue;
      short val3 = 0;
      
      Console.WriteLine("MinValue = " + val1);
      Console.WriteLine("MaxValue = " + val2);
      Console.WriteLine("Zero = " + val3);
      
      Console.WriteLine("Size of Int16: " + sizeof(short) + " bytes");
   }
}

The output of the above code is −

MinValue = -32768
MaxValue = 32767
Zero = 0
Size of Int16: 2 bytes

Using GetHashCode() Method

The GetHashCode() method returns a hash code for the current Int16 instance, useful for hash-based collections −

Example

using System;

public class Demo {
   public static void Main() {
      short val1 = 20;
      short val2 = 25;
      short val3 = 20;
      
      Console.WriteLine("Value1 = " + val1);
      Console.WriteLine("Value2 = " + val2);
      Console.WriteLine("Value3 = " + val3);
      
      Console.WriteLine("HashCode for value1 = " + val1.GetHashCode());
      Console.WriteLine("HashCode for value2 = " + val2.GetHashCode());
      Console.WriteLine("HashCode for value3 = " + val3.GetHashCode());
      
      Console.WriteLine("val1 equals val2? " + val1.Equals(val2));
      Console.WriteLine("val1 equals val3? " + val1.Equals(val3));
   }
}

The output of the above code is −

Value1 = 20
Value2 = 25
Value3 = 20
HashCode for value1 = 1310740
HashCode for value2 = 1638425
HashCode for value3 = 1310740
val1 equals val2? False
val1 equals val3? True

Using GetTypeCode() Method

The GetTypeCode() method returns the TypeCode enumeration value for the Int16 type −

Example

using System;

public class Demo {
   public static void Main() {
      short val1 = 100;
      int val2 = 100;
      long val3 = 100;
      
      TypeCode type1 = val1.GetTypeCode();
      TypeCode type2 = val2.GetTypeCode();
      TypeCode type3 = val3.GetTypeCode();
      
      Console.WriteLine("Short value: " + val1 + ", TypeCode: " + type1);
      Console.WriteLine("Int value: " + val2 + ", TypeCode: " + type2);
      Console.WriteLine("Long value: " + val3 + ", TypeCode: " + type3);
   }
}

The output of the above code is −

Short value: 100, TypeCode: Int16
Int value: 100, TypeCode: Int32
Long value: 100, TypeCode: Int64

Using Parse() Method

Example

using System;

public class Demo {
   public static void Main() {
      string str1 = "1500";
      string str2 = "-2500";
      
      short result1 = Int16.Parse(str1);
      short result2 = Int16.Parse(str2);
      
      Console.WriteLine("Parsed '" + str1 + "' to: " + result1);
      Console.WriteLine("Parsed '" + str2 + "' to: " + result2);
      
      Console.WriteLine("Sum: " + (result1 + result2));
   }
}

The output of the above code is −

Parsed '1500' to: 1500
Parsed '-2500' to: -2500
Sum: -1000

Conclusion

The Int16 struct in C# provides a 16-bit signed integer type with a range from -32,768 to 32,767. It offers essential methods for comparison, equality checking, hash code generation, and type conversion, making it suitable for memory-efficient integer operations where the value range fits within 16 bits.
