can not the "string.Empty" as the default parameter method?

Question

Hi

To all users

When the value of "string.Empty" parameter method I use, I encountered the following error:

 

Error 1 Default parameter value for 'Name' must be a compile-time constant.

 

public void SetName(string Name = string.Empty)

{

   this.mName = Name;

}

 

 

thanks.
