Pass table valued parameter using ADO.NET

How to pass table valued parameter to stored procedure using ADO.NET?

1. Create type in SQL Server:

   CREATE TYPE [dbo].[MyDataType] As Table
   (
       ID INT,
       Name NVARCHAR(50)
   )
   

2. Create Procedure:

   CREATE PROCEDURE [dbo].[MyProcedure]
   (
       @myData As [dbo].[MyDataType] Readonly
   )
   AS
   
   BEGIN
       SELECT * FROM @myData
   END
   

3. Create DataTable in C#:

   DataTable myDataTable = new DataTable("MyDataType");
   myDataTable.Columns.Add("Name", typeof(string));
   myDataTable.Columns.Add("Id", typeof(Int32));
   myDataTable.Rows.Add("XYZ", 1);
   myDataTable.Rows.Add("ABC", 2);
   

4. Create SQL Parameter:

   SqlParameter parameter = new SqlParameter();
   parameter.ParameterName = "@myData";
   parameter.SqlDbType = System.Data.SqlDbType.Structured;
   parameter.Value = myDataTable;
   command.Parameters.Add(parameter); 
   

I tried this and received the exception:

The table type parameter '@MyDataType' must have a valid type name.

I had to set the "TypeName" property of the SqlParameter:

parameter.TypeName = "MyDataType";
