While maintaining a code in a web service I came across the following code snippet:
#pragma warning disable 1591
When searching for its meaning, I did not find anything in Portuguese that was easily accessible.
Question
What is #pragma ? And when should it be used?
The #pragma is used to pass specific instructions to the compiler
To use, you must enter #pragma nome-configuracao argumentos
In the following example the warnings for the test code snippet are disabled, you may notice that there is a variable that is declared and not used, this would of course display a warning in the compilation, but since we disable it,
#pragma warning disable warning-list
public void teste(){
string naoUtiliza = "Teste";
return "Teste";
}
#pragma warning restore warning-list
# pragma provides the compiler with special instructions for compiling the file in which it is displayed. The compiler should support the instructions. In other words, you can not use #pragma to create custom preprocessing instructions. The Microsoft C # compiler supports these two #pragma statements:
#pragma warning
#pragma checksum
