Format Specifiers in C#

When you debug C# code in the Watch window or QuickWatch dialog box, you change the format in which a value is displayed using format specifiers.

To use a format specifier, type the expression followed by a comma. After the comma, add the appropriate specifier.

Suppose nVar is a character variable, and the Watch window shows the value as 0x0000F065. You want to see this value as decimal, but you do not want to reset the display of all variables to decimal. You can use the format specifier d to show the variable contents in decimal:

nVar,d

The following table shows the C# format specifiers recognized by the debugger.
