C# getting its own class name

Question

如果我有一个名为MyProgram的类，有没有办法将“ MyProgram ”作为字符串检索？

Answer 1

尝试这个：

this.GetType().Name

Answer 2

I wanted to throw this up for good measure. I think the way @micahtan posted is preferred.

typeof(MyProgram).Name

Answer 3

在 C# 6.0 中，您可以使用nameof运算符：

nameof(MyProgram)

Answer 4

Although micahtan's answer is good, it won't work in a static method. If you want to retrieve the name of the current type, this one should work everywhere:

string className = MethodBase.GetCurrentMethod().DeclaringType.Name;

Answer 5

If you need this in derived classes, you can put that code in the base class:

protected string GetThisClassName() { return this.GetType().Name; }

Then, you can reach the name in the derived class. Returns derived class name. Of course, when using the new keyword "nameof", there will be no need like this variety acts.

Besides you can define this:

public static class Extension
{
    public static string NameOf(this object o)
    {
        return o.GetType().Name;
    }
}

And then use like this:

public class MyProgram
{
    string thisClassName;

    public MyProgram()
    {
        this.thisClassName = this.NameOf();
    }
}

Answer 6

作为参考，如果您有一个从另一个继承的类型，您也可以使用

this.GetType().BaseType.Name

Answer 7

Use this

Let say Application Test.exe is running and function is foo() in form1 [basically it is class form1 ], then above code will generate below response.

string s1 = System.Reflection.MethodBase.GetCurrentMethod().DeclaringType.Name;

This will return .

s1 = "TEST.form1"

for function name:

string s1 = System.Reflection.MethodBase.GetCurrentMethod().Name;

will return

s1 = foo 

Note if you want to use this in exception use :

catch (Exception ex)
{

    MessageBox.Show(ex.StackTrace );

}

Answer 8

this can be omitted. All you need to get the current class name is:

GetType().Name

Answer 9

获取 Asp.net 的当前类名

string CurrentClass = System.Reflection.MethodBase.GetCurrentMethod().DeclaringType.Name.ToString();

Answer 10

This can be used for a generic class

typeof(T).Name

Answer 11

The easiest way is to use the call name attribute. However, currently, there is no attribute class that returns the class name or the namespace of the calling method.

See: CallerMemberNameAttributeClass

public void DoProcessing()
{
    TraceMessage("Something happened.");
}

public void TraceMessage(string message,
        [System.Runtime.CompilerServices.CallerMemberName] string memberName = "",
        [System.Runtime.CompilerServices.CallerFilePath] string sourceFilePath = "",
        [System.Runtime.CompilerServices.CallerLineNumber] int sourceLineNumber = 0)
{
    System.Diagnostics.Trace.WriteLine("message: " + message);
    System.Diagnostics.Trace.WriteLine("member name: " + memberName);
    System.Diagnostics.Trace.WriteLine("source file path: " + sourceFilePath);
    System.Diagnostics.Trace.WriteLine("source line number: " + sourceLineNumber);
}

// Sample Output:
//  message: Something happened.
//  member name: DoProcessing
//  source file path: c:\Users\username\Documents\Visual Studio 2012\Projects\CallerInfoCS\CallerInfoCS\Form1.cs
//  source line number: 31
