废话不多说，直接给大家贴C#代码了。

/// <summary>/// 执行存储过程，返回" 返回值"/// </summary>/// <param name="storedProcName">存储过程名</param>/// <param name="parameters">存储过程参数</param>/// <returns>执行存储过程的返回值</returns>public static int RunProcedureWithReturn(string storedProcName, IDataParameter[] parameters){using (SqlConnection connection = new SqlConnection(connectionString)){int result;connection.Open();SqlCommand command = BuildIntCommand(connection, storedProcName, parameters);command.ExecuteNonQuery();result = (int)command.Parameters["ReturnValue"].Value;//Connection.Close();return result;}}/// <summary>/// 创建 SqlCommand 对象实例(用来返回一个整数值) /// </summary>/// <param name="storedProcName">存储过程名</param>/// <param name="parameters">存储过程参数</param>/// <returns>SqlCommand 对象实例</returns>private static SqlCommand BuildIntCommand(SqlConnection connection, string storedProcName, IDataParameter[] parameters){SqlCommand command = BuildQueryCommand(connection, storedProcName, parameters);command.Parameters.Add(new SqlParameter("ReturnValue",SqlDbType.Int, 4, ParameterDirection.ReturnValue,false, 0, 0, string.Empty, DataRowVersion.Default, null));return command;}

ps:在C#中调用存储过程中的两种返回值

//存储过程//create proc authors_count @outrus int output//as//declare @authors int//select @authors=count(*) from authors//set @outrus=@authors//return @authorsSystem.Data.SqlClient.SqlConnection sqlcon=new System.Data.SqlClient.SqlConnection("server=(local);database=pubs;uid=sa;pwd=;");System.Data.SqlClient.SqlCommand sqlcmd=new System.Data.SqlClient.SqlCommand("authors_count",sqlcon);sqlcmd.CommandType=System.Data.CommandType.StoredProcedure;// sqlcmd.CommandText="authors_count";// sqlcmd.Connection=sqlcon;sqlcmd.Parameters.Add("@rus",System.Data.SqlDbType.Int);sqlcmd.Parameters.Add("@outrus",System.Data.SqlDbType.Int);sqlcmd.Parameters[0].Direction=System.Data.ParameterDirection.ReturnValue;sqlcmd.Parameters[1].Direction=System.Data.ParameterDirection.Output;sqlcon.Open();//int res=(int)sqlcmd.ExecuteNonQuery();//此时返回的不是存储过程的返回值，以上只是返回delete,update,insert所影响的行数sqlcmd.ExecuteNonQuery();string res=sqlcmd.Parameters[0].Value.ToString();//这样就可以得到存储过程的返回值sqlcon.Close();this.label1.Text="存储过程的返回值是:"+res.ToString();//由return 返回this.label2.Text="存储过程中返回的output值:"+sqlcmd.Parameters[1].Value.ToString();//由output返回
