C # create a stored procedure

I forgot how to call the stored procedure. Hey, record the msdn case.

using System;using System.Data;using System.Data.SqlClient;using System.Data.SqlTypes;using Microsoft.SqlServer.Server;public partial class StoredProcedures{    [SqlProcedure()]    public static void InsertCurrency_CS(        SqlString currencyCode, SqlString name)    {        using (SqlConnection conn = new SqlConnection("context connection=true"))        {            SqlCommand InsertCurrencyCommand = new SqlCommand();            SqlParameter currencyCodeParam = new SqlParameter("@CurrencyCode", SqlDbType.NVarChar);            SqlParameter nameParam = new SqlParameter("@Name", SqlDbType.NVarChar);            currencyCodeParam.Value = currencyCode;            nameParam.Value = name;            InsertCurrencyCommand.Parameters.Add(currencyCodeParam);            InsertCurrencyCommand.Parameters.Add(nameParam);            InsertCurrencyCommand.CommandText =                "INSERT Sales.Currency (CurrencyCode, Name, ModifiedDate)" +                " VALUES(@CurrencyCode, @Name, GetDate())";            InsertCurrencyCommand.Connection = conn;            conn.Open();            InsertCurrencyCommand.ExecuteNonQuery();            conn.Close();        }    }}
