C# getting its own class name
If I have a class called MyProgram
, i开发者_如何学编程s there a way of retrieving "MyProgram" as a string?
Try this:
this.GetType().Name
I wanted to throw this up for good measure. I think the way @micahtan posted is preferred.
typeof(MyProgram).Name
With C# 6.0, you can use the nameof
operator:
nameof(MyProgram)
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;
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();
}
}
For reference, if you have a type that inherits from another you can also use
this.GetType().BaseType.Name
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 );
}
this
can be omitted. All you need to get the current class name is:
GetType().Name
Get Current class name of Asp.net
string CurrentClass = System.Reflection.MethodBase.GetCurrentMethod().DeclaringType.Name.ToString();
This can be used for a generic class
typeof(T).Name
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
