class Program
{
static void Main(string[] args)
{
Program a = new Program();
a.FuncA();
Console.ReadLine();
}
int FuncA()
{
FuncB();
return 0;
}
private void FuncB()
{
MethodInfo method0 = (MethodInfo)(new StackTrace().GetFrame(0).GetMethod());
MethodInfo method1 = (MethodInfo)(new StackTrace().GetFrame(1).GetMethod());
MethodInfo method2 = (MethodInfo)(new StackTrace().GetFrame(2).GetMethod());
Console.WriteLine("Current Method is : {0}",method0.Name);
Console.WriteLine("Parent Method is : {0}", method1.Name);
Console.WriteLine("GrandParent Method is : {0}", method2.Name);
}
}
{
static void Main(string[] args)
{
Program a = new Program();
a.FuncA();
Console.ReadLine();
}
int FuncA()
{
FuncB();
return 0;
}
private void FuncB()
{
MethodInfo method0 = (MethodInfo)(new StackTrace().GetFrame(0).GetMethod());
MethodInfo method1 = (MethodInfo)(new StackTrace().GetFrame(1).GetMethod());
MethodInfo method2 = (MethodInfo)(new StackTrace().GetFrame(2).GetMethod());
Console.WriteLine("Current Method is : {0}",method0.Name);
Console.WriteLine("Parent Method is : {0}", method1.Name);
Console.WriteLine("GrandParent Method is : {0}", method2.Name);
}
}
程序的输出结果是:
Current Method is : FuncB
Parent Method is : FuncA
GrandParent Method is : Main
其中调用GetFrame得到栈空间,参数index 表示栈空间的级别,0表示当前栈空间,1表示上一级的栈空间,依次类推。
除了可以获取方法信息外,还可以调用StackFrame类的成员函数,在运行时得到代码的文件信息及行号和列号等。详情可以参考msdn上的一个example
// Display the stack frame properties.
StackFrame sf = st.GetFrame(i);
Console.WriteLine(" File: {0}", sf.GetFileName());
Console.WriteLine(" Line Number: {0}",
sf.GetFileLineNumber());
// Note that the column number defaults to zero
// when not initialized.
Console.WriteLine(" Column Number: {0}",
sf.GetFileColumnNumber());
if (sf.GetILOffset() != StackFrame.OFFSET_UNKNOWN)
{
Console.WriteLine(" Intermediate Language Offset: {0}",
sf.GetILOffset());
}
if (sf.GetNativeOffset() != StackFrame.OFFSET_UNKNOWN)
{
Console.WriteLine(" Native Offset: {0}",
sf.GetNativeOffset());
}
