过程或函数SP_XXX指定了太多参数
我正在处理一些项目并得到此错误消息：
*过程或函数SP_XXX指定的参数太多*下面是我的SQL参数即时通过ASP c＃应用程序检查了很多站点并且什么也没得到:)非常感谢您的帮助！

抱歉错误的post
其次，我按如下方式运行了c＃代码：
public class MemberD { public SqlCommand cmd = new SqlCommand(); public SqlConnection con = new SqlConnection("ConStr"); public SqlDataReader dr; public void UpdateMember(string CODE, int COCODE, Member user) { cmd.Parameters.Clear(); // Here's the solution //Here I added my SQL parameters cmd.CommandType = System.Data.CommandType.StoredProcedure; cmd.CommandText = "SP_MSMEMBERS_UPDATE"; cmd.Connection = con; con.Open(); cmd.ExecuteNonQuery(); con.Close(); } }
关键是我使用SqlCommand作为全局变量启动一次因此当我使用Update方法两次或例如GetByID方法时，SQLCommand变量也保留旧参数。 因此，当您传递超过SP需要的参数时，您会收到上述错误，因此我只需添加： cmd.Parameters.Clear（）; 在每个方法的开头。
现在它的工作正常。
该错误通常表示具有比SP定义的更多参数。
由于您没有提供足够的代码来告诉您（提供更多的cmd代码块和至少SP的定义），我认为就是这种情况。 特别是提供了这么多论点。
我确实读过这也是处理SqlDatasources时可能遇到的问题。 但是，由于您提供的代码有限，我只是指出了这种可能性。
