Assembly: Microsoft.VisualStudio.TextManager.Interop (in Microsoft.VisualStudio.TextManager.Interop.dll)

Syntax

声明
Function GetSize ( _
    <OutAttribute> ByRef piLength As Integer _
) As Integer

int GetSize(
    out int piLength
)

int GetSize(
    [OutAttribute] int% piLength
)

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.

Implements

IVsTextBuffer.GetSize(Int32%)

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.
