How to Pass Table-Valued Parameters to SQL Server Stored Procedures Using ADO.NET?

Efficient Data Transfer with ADO.NET and Table-Valued Parameters

ADO.NET provides a streamlined approach to managing data transfer when interacting with SQL Server stored procedures that utilize table-valued parameters. Here's how to effectively pass these parameters:

1. Defining the SQL Server Table Type: Begin by creating a user-defined table type in SQL Server using the CREATE TYPE command. This type defines the structure of your table-valued parameter.

2. Creating the Stored Procedure: Next, construct a stored procedure that accepts a table-valued parameter of the type you've defined.

3. Building the DataTable in C#: Within your C# application, create a DataTable that mirrors the structure of the table-valued parameter defined in SQL Server.

4. Configuring the SQL Parameter: Finally, create an SqlParameter object. Set its ParameterName to match the stored procedure's parameter name, its SqlDbType to Structured, and assign your DataTable to its Value property.

This method ensures efficient data handling and allows for complex queries and manipulations when working with SQL Server stored procedures and ADO.NET.
