'使用
Dim instance As IVsTextStream

abstract GetSize :
piLength:int byref -> int
function GetSize(
piLength : int
) : int
Parameters
- piLength
Type: System.Int32%
[out] Pointer to the size of the buffer, which is not necessarily the same value as the size of the buffer's internally-allocated memory or the size of the file (if any) represented by the buffer.
Return Value
Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks
COM Signature
From textmgr.idl:
HRESULT IVsTextStream::GetSize(
[out] long *piLength
);
This method could require considerable resources, depending upon the underlying implementation of the buffer. That is, it could be very difficult to calculate the size of the buffer if it is a virtual-line-oriented implementation of the buffer, as in Visual Basic.
