谁能帮我看看！

SqlConnection conn = new SqlConnection("server=localhost;pwd = sun,user id ='sa',database = test,Integrated Security=SSPI");
                    
                conn.Open();

                SqlCommand cmd = new SqlCommand();

                = "INSERT INTO test(city,tq,wd) VALUES ('qq','" + YQ + "','" + WD + "')";

                cmd.Connection = conn;

                cmd.ExecuteNonQuery();

                MessageBox.Show("数据添加成功!");

                conn.Close();

SqlConnection conn = new SqlConnection("server=localhost;pwd = sun,user id =sa,database = test,Integrated Security=SSPI");

Persist Security Info=False;User ID=sa;Password=sun;Initial Catalog=test;Server=.;Integrated Security=SSPI

Integrated Security=SSPI这个是集成登陆，你先前又写了SQL Server登陆模式。。。

conn.Open();

 cmd.ExecuteNonQuery();

 MessageBox.Show("数据添加成功!");

 conn.Close();
我想Open()应放这

将server改为data source

打开企业管理器,local--右键--属性--安全性,身份验证选择sql server和windows

Data Source=.;Initial Catalog=test;User ID=sa;Password=sun

去掉Integrated Security=SSPI

open()....



绝对不是这的问题...
