StackFrame.GetNativeOffset 方法

定义

命名空间:

System.Diagnostics

程序集:

System.Diagnostics.StackTrace.dll

Source:

StackFrame.cs

获取相对于所执行方法的本机实时 (JIT) 编译代码开头的偏移量。 该调试信息的生成受 DebuggableAttribute 类控制。

public:
 virtual int GetNativeOffset();

public virtual int GetNativeOffset ();

abstract member GetNativeOffset : unit -> int
override this.GetNativeOffset : unit -> int

Public Overridable Function GetNativeOffset () As Integer

返回

Int32

相对于所执行方法的 JIT 编译代码开头的偏移量。

示例

下面的示例演示 GetNativeOffset 方法的用法。 此代码示例是为 StackFrame 类提供的一个更大示例的一部分。

// Display the stack frame properties.
StackFrame^ sf = st->GetFrame( i );
Console::WriteLine( " File: {0}", sf->GetFileName() );
Console::WriteLine( " Line Number: {0}", sf->GetFileLineNumber().ToString() );

// Note that the column number defaults to zero
// when not initialized.
Console::WriteLine( " Column Number: {0}", sf->GetFileColumnNumber().ToString() );
Console::WriteLine( " Intermediate Language Offset: {0}", sf->GetILOffset().ToString() );
Console::WriteLine( " Native Offset: {0}", sf->GetNativeOffset().ToString() );

// 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());
}

' Display the stack frame properties.
Dim sf As StackFrame = st.GetFrame(i)
Console.WriteLine(" File: {0}", sf.GetFileName())
Console.WriteLine(" Line Number: {0}", _
   sf.GetFileLineNumber())
' 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())
End If
If sf.GetNativeOffset <> StackFrame.OFFSET_UNKNOWN
  Console.WriteLine(" Native Offset: {0}", _
      sf.GetNativeOffset())
End If
