C#中調用存儲過程：帶輸入輸出參數

using (SqlConnection conn = new SqlConnection(this.GetConnectionString(this.WMPDBName)))
{
SqlCommand cmd = conn.CreateCommand();

cmd.CommandType = System.Data.CommandType.StoredProcedure;
cmd.CommandText = "存儲過程名稱";

////輸出參數
cmd.Parameters.Add(new SqlParameter("@DeleteTotal", System.Data.SqlDbType.Int));
cmd.Parameters["@DeleteTotal"].Direction = System.Data.ParameterDirection.Output;
cmd.Parameters.Add(new SqlParameter("@InsertTotal", System.Data.SqlDbType.Int));
cmd.Parameters["@InsertTotal"].Direction = System.Data.ParameterDirection.Output;

//// 輸入參數【方式一】
cmd.Parameters.Add(new SqlParameter("@PageIndex", System.Data.SqlDbType.Int));
cmd.Parameters["@PageIndex"].Direction = System.Data.ParameterDirection.Input;
cmd.Parameters["@PageIndex"].Value = 1;

//// 輸入參數【方式二】
cmd.Parameters.Add(new SqlParameter("@PageIndex", 1));
conn.Open();
cmd.ExecuteNonQuery();
int.TryParse(cmd.Parameters["@DeleteTotal"].Value.ToString(), out deleteTotal);
int.TryParse(cmd.Parameters["@InsertTotal"].Value.ToString(), out insertTotal);
}
