Get Stored Procedure from Data Context : Linq to SQl

Question

I have a stored procedure named ParseXML in SQL Server. I have a repository pattern using LINQ to SQL. I need to call the stored procedure from within the repository layer.

You can do something like this, calling the method using reflection:

var inputXML = GetXML(); 

var method = Context.GetType().GetMethod("ParseXML");

if(method == null) throw new InvalidOperationException("Defined DataContext does not have method ParseXML");

var result = method.Invoke(Context, new object[]{ inputXML });

If you are using c# 4.0, you can do:

var inputXML = GetXML(); 

dynamic dynamicContext = Context;

var result = (ISingleResult)dynamicContext.ParseXML(inputXML);
