Version Used:
VS17.3p2
Steps to Reproduce:
Type code like below (I use tabs to trigger the bug, but using spaces may also trigger):
using System;
switch (getVirtualKey())
{
case VirtualKey.Up or VirtualKey.Down or VirtualKey.Left or VirtualKey.Right:
{
}
}
// A local function to simulate get operation.
static VirtualKey getVirtualKey() => VirtualKey.Up;
enum VirtualKey
{
Up,
Down,
Left,
Right
}
Then I input a open square bracket [ after the colon token : case label, the highlight will be messed up:
using System;
switch (getVirtualKey())
{
// Insert '[' here
// ↓
case VirtualKey.Up or VirtualKey.Down or VirtualKey.Left or VirtualKey.Right: [
{
}
}
// A local function to simulate get operation.
static VirtualKey getVirtualKey() => VirtualKey.Up;
enum VirtualKey
{
Up,
Down,
Left,
Right
}
It seems that the syntax highlight has been messed up.
See sharplab
If the same operation is applied to the sharplab, the information will be incorrect:
Step 1:
Step 2 (Add '[' token):
Step 3 (Press Ctrl + Z to undo):
The error info is different with the original case.
Expected Behavior:
The syntax is wrong but the info and syntax highlighter behave as normal.
Actual Behavior:
The syntax is wrong, but it seems that the syntax highlighter is broken.
