How do you parse large SQL scripts in batches?

I have a very large sql file that I want to split into batches for execution. I want to make sure that I parse it the same way as SSMS and SQLCMD.

Microsoft has an excellent build in mixed mode called Microsoft.SqlServer.BatchParser with the Parser class, which seams as if it would be a trick.

He wants to implement IBatchSource as an argument to SetBatchSource before calling Parse ().

Where can I find an implementation of IBatchSource and additional information on how to use this functionality?

Microsoft.SqlServer.BatchParser GAC Microsoft.SqlServer.BatchParserClient, IBatchSource.

namespace Microsoft.SqlServer.Management.Common
{
  internal class BatchSourceFile : IBatchSource
  internal class BatchSourceString : IBatchSource
}

.

: ! Microsoft.SqlServer.Management.Common.ExecuteBatch. StringCollection GetStatements ( sqlCommand)?

Me: , , BatchParserClient assembly. , !
