Gets the Guid value stored in the PipelineBuffer column.
Assembly: Microsoft.SqlServer.PipelineHost (in Microsoft.SqlServer.PipelineHost.dll)
This method works with the DT_GUID data type in Integration Services.
If the value of the column is null, the PipelineBuffer produces a ColumnIsNullException. You should first check for null by calling the IsNull method before retrieving the Guid from the buffer column.
