Calling Stored Proc With LINQ And Passing In DataTable?

Trying to pass in my DataTable to a stored proc using LINQ. Below is my code.

var sqlCommand = new System.Data.SqlClient.SqlCommand {
CommandType = System.Data.CommandType.StoredProcedure,
CommandText = "UserIdList"
};
var dataTable = new System.Data.DataTable("IdList");
dataTable.Columns.Add("AttributeIds", typeof(Int32));
dataTable.Rows.Add(26);
dataTable.Rows.Add(40);
dataTable.Rows.Add(41);
dataTable.Rows.Add(45);
dataTable.Rows.Add(78);
dataTable.Rows.Add(33);
dataTable.Rows.Add(36);
//The parameter for the SP must be of SqlDbType.Structured
var parameter = new System.Data.SqlClient.SqlParameter {
ParameterName = "@AttributeIds",
SqlDbType = System.Data.SqlDbType.Structured,
TypeName = "ecs.IDList",
Value = dataTable,
};
sqlCommand.Parameters.Add(parameter);
var user = myDC.DC.ExecuteQuery("exec ecs.udpUserAttributeDetails {0}, {1}", sqlCommand, userId).SingleOrDefault();
