C# 在C中读取输出sql server存储过程参数#

我希望SQLServer2008中inserts语句有两个输出ID。我相信我在初始化AddParam时犯了一些错误，因为它没有插入数据。存储过程本身，也包括没有参数的代码，都经过了测试并正常工作

存储过程 视图模型 我需要帮助的班级

将

@StatementAnswerID

和

@ElectronicSignatureID

设置为输出参数：

cmd.Parameters("@StatementAnswerID").Direction = ParameterDirection.Output;
cmd.Parameters("@ElectronicSignatureID").Direction = ParameterDirection.Output;

执行存储过程。 全文如下：

cmd.Parameters("@StatementAnswerID").Value;
cmd.Parameters("@ElectronicSignatureID").Value;

你收到错误信息了吗？
