从c＃ExecuteNonQuery（）更新sql-command字符串;

Question

应用可行，但通过WPF更新无效

string sqlIns = "UPDATE Team_table SET result1 = '4:2' where name1=@Team1 and name2=@Team1";    
string Team1_string = Team1.Text;

// Team1，Team2，result1，result2是TextBox控件的名称

cmdIns.Parameters.AddWithValue("@Team1", Team1_string);
string Team2_string = Team2.Text;
cmdIns.Parameters.AddWithValue("@Team2", Team2_string);
string result1_string = Result1.Text;
cmdIns.Parameters.AddWithValue("@result1", result1_string);

如何运作？

Answer 1

除非您在团队自己玩游戏时更新行，否则错误来自：

name1=@Team1 and name2=@Team1

我非常赞同你的意思

name1=@Team1 and name2=@Team2

Answer 2

您没有正确设置连接字符串到SqlConnection对象

替换为：

SqlConnection con = new SqlConnection(TTKZS);

以下内容：

 SqlConnection con = new SqlConnection(hhconn);
