How to execute a stored procedure within C# program

How to execute a stored procedure within C# program

To execute a stored procedure within a C# program, you can use the SqlCommand class provided by the System.Data.SqlClient namespace. Here's an example code snippet that demonstrates how to execute a stored procedure named myStoredProcedure:

 using System.Data.SqlClient; string connectionString = "Data Source=myServerAddress;Initial Catalog=myDataBase;User ID=myUsername;Password=myPassword;"; string storedProcedureName = "myStoredProcedure"; using (SqlConnection connection = new SqlConnection(connectionString)) { SqlCommand command = new SqlCommand(storedProcedureName, connection); command.CommandType = CommandType.StoredProcedure; // Set parameter values, if any command.Parameters.AddWithValue("@parameterName", parameterValue); connection.Open(); command.ExecuteNonQuery(); }

In this example, a SqlConnection object is created with the connection string. Then, a SqlCommand object is created with the name of the stored procedure and the connection object. The CommandType property is set to CommandType.StoredProcedure to indicate that the command is a stored procedure.

If the stored procedure has parameters, you can set their values using the Parameters.AddWithValue method before executing the command. Finally, the connection is opened and the command is executed using the ExecuteNonQuery method.

Note that you should always use parameterized queries or stored procedures to avoid SQL injection attacks.
