如何獲取父方法名稱？

我正在使用NUnit和Selenium WebDriver編寫Web測試。在每次測試結束時，我想獲取瀏覽器的屏幕截圖並保存圖像。我希望圖像名稱與Test名稱相同。但我無法獲得測試方法名稱。如何獲取父方法名稱？

這裏是測試方法：

[Test] 
public void AbcTest_ShouldPass() 
{ 
    Assert.AreEqual(true, true); 
}

這裏的每個Test後運行TearDown：

[TearDonw] 
[MethodImpl(MethoImplOptions.NoInlining)] 
public void TestCleanupNunit() 
{ 
    var methodName = new List<string>(); 
    for (int i = 0; i < 30; i++) 
     methodName.Add(i.ToString() + " is " + new StackTrace(i, true).GetFrame(0).GetMethod().Name); 

}

，但是當我看methodName，我找不到AbcTest_ShouldPass。

0 is TestCleanupNUnit 
1 is InvokeMethod 
2 is UnsafeInvokeInternal 
3 is Invoke 
4 is Invoke 
5 is InvokeMethod 
6 is InvokeMethod 
7 is RunTearDown 
8 is RunTest 
9 is RunTest 
10 is RunRepeatedTest 
11 is RunTestInContext 
12 is Run 
13 is RunAllTests 
14 is RunSuite 
15 is RunSuiteInContext 
16 is Run 
17 is Run 
18 is RunAllTests 
19 is RunSuite 
20 is RunSuiteInContext 
21 is Run 
22 is RunAllTests 
23 is RunSuite 
24 is RunSuiteInContext 
25 is Run 
26 is RunAllTests 
27 is RunSuite 
28 is RunSuiteInContext 
29 is Run

我看着這個post，但它並沒有幫助我。
