特性CallerMemberName

开发过程中，我们有时候需要记录一下调用信息

 1 public static void TraceMessage(string message,
 2             [CallerMemberName] string memberName="",
 3             [CallerFilePath] string sourceFilePath="",
 4             [CallerLineNumber] int sourceLineNumber=0)
 5 {
 6      Console.WriteLine($"message:{message}\nmember name: {memberName}" +
 7      $"\nsource file path: {sourceFilePath}\nsource line number: {sourceLineNumber}");
 8 }
 9 
10 
11 public void DoSomething()
12 {
13      TraceMessage("事情开始起变化!");
14 }

调用DoSomething的结果如下

message:事情开始起变化!
member name: DoSomething //调用函数（准确讲应该是成员）名称
source file path: /Users/qinyuanlong/DotNet_core_x1/CallerMemberNameConsole/CallerMemberNameConsole/Program.cs //调用文件
source line number: 16 //调用行号
