Call a stored procedure with parameter in c#

Call a stored procedure with parameter in c#

To call a stored procedure with parameters in C#, you can use the SqlCommand class provided by ADO.NET. Here is an example:

 using (SqlConnection connection = new SqlConnection(connectionString)) { using (SqlCommand command = new SqlCommand("YourStoredProcedureName", connection)) { command.CommandType = CommandType.StoredProcedure; // Add parameters to the command command.Parameters.Add(new SqlParameter("@Param1", value1)); command.Parameters.Add(new SqlParameter("@Param2", value2)); // Open the connection connection.Open(); // Execute the command command.ExecuteNonQuery(); // Close the connection connection.Close(); } } 

In this example, connectionString is a string that contains the connection information for the database, YourStoredProcedureName is the name of the stored procedure you want to call, @Param1 and @Param2 are the names of the parameters in the stored procedure, and value1 and value2 are the values you want to pass to the stored procedure.

You can also use the ExecuteScalar method of the SqlCommand class to retrieve a single value from the stored procedure, or the ExecuteReader method to retrieve a result set.
