本文实例讲述了asp.net实现调用存储过程并带返回值的方法。,具体如下:
/// <summary>/// DataBase 的摘要说明/// </summary>public class DataBase{ /// <summary> ///DataBase 的摘要说明 /// </summary> protected static SqlConnection BaseSqlConnection = new SqlConnection();//连接对象 protected SqlCommand BaseSqlCommand = new SqlCommand(); //命令对象 public DataBase() { // // TODO: 在此处添加构造函数逻辑 // } protected void OpenConnection() { if (BaseSqlConnection.State == ConnectionState.Closed) //连接是否关闭 try { BaseSqlConnection.ConnectionString = ConfigurationManager.ConnectionStrings["productsunion"].ToString(); BaseSqlCommand.Connection = BaseSqlConnection; BaseSqlConnection.Open(); } catch (Exception ex) { throw new Exception(ex.Message); } } public void CloseConnection() { if (BaseSqlConnection.State == ConnectionState.Open) { BaseSqlConnection.Close(); BaseSqlConnection.Dispose(); BaseSqlCommand.Dispose(); } } public bool Proc_Return_Int(string proc_name, params SqlParameter[] cmdParms) { try { OpenConnection(); if (cmdParms != null) { foreach (SqlParameter parameter in cmdParms) { if ((parameter.Direction == ParameterDirection.InputOutput || parameter.Direction == ParameterDirection.Input) && (parameter.Value == null)) { parameter.Value = DBNull.Value; } BaseSqlCommand.Parameters.Add(parameter); } BaseSqlCommand.CommandType = CommandType.StoredProcedure; BaseSqlCommand.CommandText = proc_name; BaseSqlCommand.ExecuteNonQuery(); if (BaseSqlCommand.Parameters["Return"].Value.ToString()== "0") { return true; } else { return false; } } else { return false; } } catch { return false; } finally { BaseSqlCommand.Parameters.Clear(); CloseConnection(); } }}
加入了一个组合类
public class SqlModel:ISqlModel{ #region ISqlModel 成员 public bool Proc_Return_Int(string proc_name, string[,] sArray) { try { if (sArray.GetLength(0) >= 1) { DataBase db = new DataBase(); SqlParameter[] sqlpar = new SqlParameter[sArray.GetLength(0)+1];//加入返回值 for (int i = 0; i < sArray.GetLength(0); i++) { sqlpar[i] = new SqlParameter(sArray[i,0], sArray[i,1]); } sqlpar[sArray.GetLength(0)] = new SqlParameter("Return", SqlDbType.Int); sqlpar[sArray.GetLength(0)].Direction = ParameterDirection.ReturnValue; if (db.Proc_Return_Int(proc_name, sqlpar)) { return true; } else { return false; } } else { return false; } } catch { return false; } } #endregion}
