对于特定的类字段,在C#中禁用/禁止警告CS0649

Question

我在C#类中有一些字段,我使用反射初始化.编译器显示CS0649警告:

Field foo' is never assigned to, and will always have its default valuenull'(CS0649)(Assembly-CSharp)

我想仅禁用这些特定字段的警告,并仍然显示该类的其他类和其他字段的警告.可以为整个项目禁用CS0649,还有更细粒度的东西吗？

Answer 1

您可以使用#pragma warning禁用然后重新启用特定警告:

public class MyClass
{
    #pragma warning disable 0649

    // field declarations for which to disable warning
    private object foo;

    #pragma warning restore 0649

    // rest of class
}

有关扩展答案,请参阅C#中的抑制"永不使用"和"永不分配"警告.

Answer 2

我相信值得注意的是,使用字段初始化程序也可以抑制警告.这会使您的代码更加混乱.

public class MyClass
{
    // field declarations for which to disable warning
    private object foo = null;

    // rest of class
}

Answer 3

//disable warning here
#pragma warning disable 0649

 //foo field declaration

//restore warning to previous state after
#pragma warning restore 0649

Answer 4

public class YouClass
{
#pragma warning disable 649
    string foo;
#pragma warning restore 649
}
