#pragma warning (C# Reference)

#pragma warning can enable or disable certain warnings.

#pragma warning disable warning-list
#pragma warning restore warning-list


  • warning-list
    A comma-separated list of warning numbers. Enter the numbers alone, without the "CS" prefix.

    When no warning numbers are specified, disable disables all warnings and restore enables all warnings.


    To find warning numbers in Visual Studio, build your project and then look for the warning numbers in the Output window.


// pragma_warning.cs
using System;

#pragma warning disable 414, 3021
public class C
    int i = 1;
    static void Main()
#pragma warning restore 3021
[CLSCompliant(false)]  // CS3021
public class D
    int i = 1;
    public static void F()
