问题描述

我想用用户输入更新我的数据库，我已经这样写了插入内容:

I wanna to Update my data base with user input , I have written the insert like this :

SqlConnection con = new SqlConnection();
con.ConnectionString= ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString;

SqlCommand com = new SqlCommand();
com.Connection = con;
com.CommandText = "Insert into tbl_Users (UserName,Passwrd,Email) values (@input1,@input2,@input3)";

com.Parameters.AddWithValue("Input1", txtU.Text);
com.Parameters.AddWithValue("input2", txtP.Text);
com.Parameters.AddWithValue("input3", txtE.Text);

try
{
    con.Open();

    com.ExecuteNonQuery();
}
catch (SqlException ex)
{
    Response.Write(ex.Message);
}
finally
{
    con.Close();
}
