C# Language C# 5.0 Features Caller Information Attributes
Example
C.I.A.s are intended as a simple way of getting attributes from whatever is calling the targeted method. There is really only 1 way to use them and there are only 3 attributes.
Example:
//This is the "calling method": the method that is calling the target method
public void doProcess()
{
GetMessageCallerAttributes("Show my attributes.");
}
//This is the target method
//There are only 3 caller attributes
public void GetMessageCallerAttributes(string message,
//gets the name of what is calling this method
[System.Runtime.CompilerServices.CallerMemberName] string memberName = "",
//gets the path of the file in which the "calling method" is in
[System.Runtime.CompilerServices.CallerFilePath] string sourceFilePath = "",
//gets the line number of the "calling method"
[System.Runtime.CompilerServices.CallerLineNumber] int sourceLineNumber = 0)
{
//Writes lines of all the attributes
System.Diagnostics.Trace.WriteLine("Message: " + message);
System.Diagnostics.Trace.WriteLine("Member: " + memberName);
System.Diagnostics.Trace.WriteLine("Source File Path: " + sourceFilePath);
System.Diagnostics.Trace.WriteLine("Line Number: " + sourceLineNumber);
}
Example Output:
//Message: Show my attributes.
//Member: doProcess
//Source File Path: c:\Path\To\The\File
//Line Number: 13
