Entity Framework - Execute Stored Procedures With Table Valued Patameter

Question

How to pass a table valued parameter to a stored procedure in Entity Framework using ExecuteSqlCommand or SqlQuery method?
Following is my code - 
DataTable dataTable=new DataTable();
dataTable.Columns.Add("col1", typeof(int));
dataTable.Columns.Add("col2", typeof(bool));
dbContext.Database.ExecuteSqlCommand("exec stored_proc @tvp",
                        new SqlParameter() { SqlDbType = SqlDbType.Structured, ParameterName = "@tvp", Value = dataTable }
This throws an exception saying 'The table type parameter '@tvp' must have a valid type name.'

Answer 1

You must set the TypeName property of the SqlParameter to the name of your table type that you have defined in the database:
SqlParameter param = new SqlParameter();
param.SqlDbType = SqlDbType.Structured;
param.ParameterName = "@tvp";
param.TypeName = "dbo.YourTableType";
param.Value = dataTable;
dbContext.Database.ExecuteSqlCommand("exec stored_proc @tvp", param);
Of course you must define the table type in the database first:
CREATE TYPE dbo.YourTableType AS TABLE
( col1 int, col1 bit )
