Is there a way to suppress warnings in C# similar to Java's @SuppressWarnings annotation?

Question

Is there a way to suppress warnings in C# similar to Java's @SuppressWarnings annotation?

Failing that, is there another way to suppress warnings in Visual Studio?

Answer 1

You could check #pragma directives: http://msdn.microsoft.com/en-us/library/441722ys%28VS.80%29.aspx.

Answer 2

There is. See the MSDN page on how to suppress compiler warnings.

From Visual Studio, go to your project properties, select the build tab, and enter the warning number in the Suppress Warnings field.

From code, to disable specific warnings, you can use the #pragma directive:

public class MyClass
{
  #pragma warning disable 0168
  // code

  // optionally, restore warnings again
  #pragma warning restore 0168
  // more code
}

Answer 3

Yes.

For disabling, use:

#pragma warning disable 0169, 0414, anyothernumber

Where the numbers are the identifiers of the warnings that you can read from compiler output.

To reenable the warnings after a particular part of code (which is a good idea) use:

#pragma warning restore 0169, anythingelse

This way you can make the compiler output clean, and keep yourself safe because the warnings will only be suppressed for that particular part of code (where you made sure you don't need to see them).

Answer 4

Yes there is you can use the pragma warning annotation like this:

#pragma warning disable 414
//some code that generates a warning
#pragma warning restore 414

omitting the numbers disables and restores all warning codes...

Answer 5

I guess you could also try to review the project or solution properties and set your warning level to a lower level or so. Otherwise, the other responses are perhaps better.
