c# print the class name from within a static function

Question

Is it possible to print the class name from within a static function?

e.g ...

public class foo
{

    static void printName()
    {
        // Print the          


        

Answer 1

Since static methods cannot be inherited the class name will be known to you when you write the method. Why not just hardcode it?

Answer 2

A (cleaner, IMO) alternative (still slow as hell and I would cringe if I saw this in a production code base):

Console.WriteLine(MethodBase.GetCurrentMethod().DeclaringType);

By the way, if you're doing this for logging, some logging frameworks (such as log4net) have the ability built in. And yes, they warn you in the docs that it's a potential performance nightmare.

Answer 3

You have three options to get the type (and therefore the name) of YourClass that work in a static function:

1. typeof(YourClass) - fast (0.043 microseconds)

2. MethodBase.GetCurrentMethod().DeclaringType - slow (2.3 microseconds)

3. new StackFrame().GetMethod().DeclaringType - slowest (17.2 microseconds)

If using typeof(YourClass) is not desirable, then MethodBase.GetCurrentMethod().DeclaringType is definitely the best option.

Answer 4

Console.WriteLine(new StackFrame().GetMethod().DeclaringType);

Answer 5

StackTrace class can do that.

Answer 6

Since C# 6.0 there exists an even simpler and faster way to get a type name as a string without typing a string literal in your code, using the nameof keyword:

public class Foo
{
    static void PrintName()
    {
        string className = nameof(Foo);
        ...
    }
}
