声明
<DispIdAttribute(105)> _
Sub GetData ( _
    <InAttribute> dwOffset As UInteger, _
    <InAttribute> ByRef lpPointer As Byte, _
    <InAttribute> dwLength As UInteger, _
    <OutAttribute> ByRef lpdwWritten As UInteger _
)

[DispIdAttribute(105)] 
void GetData (
    [InAttribute] uint dwOffset,
    [InAttribute] ref byte lpPointer,
    [InAttribute] uint dwLength,
    out uint lpdwWritten
)

[DispIdAttribute(105)] 
void GetData (
    [InAttribute] unsigned int dwOffset, 
    [InAttribute] unsigned char% lpPointer, 
    [InAttribute] unsigned int dwLength, 
    [OutAttribute] unsigned int% lpdwWritten
)

/** @attribute DispIdAttribute(105) */ 
void GetData (
    /** @attribute InAttribute() */ UInt32 dwOffset, 
    /** @attribute InAttribute() */ /** @ref */ byte lpPointer, 
    /** @attribute InAttribute() */ UInt32 dwLength, 
    /** @attribute OutAttribute() */ /** @ref */ UInt32 lpdwWritten
)
