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
}
