Caller info attributes
suggest changeCaller info attributes can be used to pass down information about the invoker to the invoked method. The declaration looks like this:
using System.Runtime.CompilerServices;
public void LogException(Exception ex,
[CallerMemberName]string callerMemberName = "",
[CallerLineNumber]int callerLineNumber = 0,
[CallerFilePath]string callerFilePath = "")
{
//perform logging
}
And the invocation looks like this:
public void Save(DBContext context)
{
try
{
context.SaveChanges();
}
catch (Exception ex)
{
LogException(ex);
}
}
Notice that only the first parameter is passed explicitly to the LogException
method whereas the rest of them will be provided at compile time with the relevant values.
The callerMemberName
parameter will receive the value "Save"
- the name of the calling method.
The callerLineNumber
parameter will receive the number of whichever line the LogException
method call is written on.
And the ‘callerFilePath’ parameter will receive the full path of the file Save
method is declared in.
Found a mistake? Have a question or improvement idea?
Let me know.
