getting the name of the calling method
提问by zeocrash
Basically i've got a web service that i'm trying to put some kind of usage logging in. To do this i've created a class with a logging method. I instatiate the class on the service and then call the logging method in each of the web methods.
基本上，我有一个 Web 服务，我正在尝试将某种用法登录。为此，我创建了一个带有日志记录方法的类。我在服务上建立类，然后在每个 Web 方法中调用日志记录方法。
I'm trying to find a way of getting the name of the method that has called the loggong method
我试图找到一种方法来获取调用 loggong 方法的方法的名称
Public sub tstmethod
log_object.log_method
end sub
in this case the returned name i'm looking for is "tstmethod"
在这种情况下，我要查找的返回名称是“tstmethod”
Everywhere i've seen has said to either use
我见过的每个地方都说要么使用
Dim stackframe As New Diagnostics.StackFrame
Return stackframe.GetMethod.Name.ToString
Or to use
或者使用
Dim stackframe As New Diagnostics.StackFrame
Return stackframe.GetMethod.DeclaringType.FullName
which i call inside the logging method
我在日志记录方法中调用
getmethod.name.tostring returns the name of the logging method
getmethod.name.tostring 返回日志记录方法的名称
getmethod.declaringtype.fullname returns the name of the logging class
getmethod.declaringtype.fullname 返回日志类的名称
no matter what i do i cannot find a way of getting the name of the method that called the logging method in this case "tstmethod"
无论我做什么，我都找不到一种方法来获取在这种情况下调用日志记录方法的方法的名称“tstmethod”

You need to instantiate the StackFramewith an appropriate constructor. For example,
您需要StackFrame使用适当的构造函数实例化。例如，
Dim stackframe As New Diagnostics.StackFrame(1)
will skip one stack frame (the logging method itself) and get the frame for the caller of that method.
将跳过一个堆栈帧（日志记录方法本身）并获取该方法调用者的帧。
That said - if at all possible, I'd strongly recommend using a standard logging mechanism such as log4net.
也就是说 - 如果可能的话，我强烈建议使用标准日志记录机制，例如log4net。

I think the above statement can be made into one single line:
我认为上面的语句可以写成一行：
MsgBox((New System.Diagnostics.StackTrace).GetFrame(1).GetMethod.Name)
This will display a Message Box as with calling method name.
这将显示一个带有调用方法名称的消息框。

You should be able to get this from the StackFrame with the constructor telling it how many frames to go up the chain, so getting the parent would use 1 (the frame is zero based, so 0 is the current method):
您应该能够从 StackFrame 获取它，构造函数告诉它在链上有多少帧，因此获取父级将使用 1（该帧是基于零的，因此 0 是当前方法）：
Dim stackTrace as New Diagnostics.StackFrame(1)
Return stackTrace.GetMethod.Name

I am using using this code for getting the calling method
我正在使用此代码获取调用方法
string methodName = new StackFrame( 1, true ).GetMethod().Name;
methodName = " [" + methodName + "]";
return methodName;
remember to add namespace Diagnostics
记得添加命名空间诊断

I add the calling form as the first parameter for all sub routines and functions like calledfunction(me,para1,para2......) so that i can identify the calling form and use its name or text in the called routine
我将调用表单添加为所有子例程和函数的第一个参数，例如 callfunction(me,para1,para2......) 以便我可以识别调用表单并在被调用例程中使用其名称或文本

Do not try using StackFrame. It will work only in debug mode which is a killer for application speed.
不要尝试使用 StackFrame。它只能在调试模式下工作，这是应用程序速度的杀手。
There is no way you can get this info in Release mode, you should consider changing design and adding parameter.
在发布模式下您无法获得此信息，您应该考虑更改设计和添加参数。
