Question

我有一个代码将数据从asp.net（c＃代码）移动到sql。在下面的代码中，我直接插入了值（即）xxx和yyy。这也有效。现在我想插入在文本框中输入的值。这样做的代码是什么？帮帮我朋友。

protected void Button2_Click(object sender, EventArgs e)
{ 
    string  comm="insert into login values('xxx','yyy')";
    con = new SqlConnection();
    con.ConnectionString = ConfigurationManager.ConnectionStrings["con"].ConnectionString.ToString();
    cmd = new SqlCommand(comm, con);
    cmd.Connection.Open();
    con.Open();
    int i = cmd.ExecuteNonQuery();
    cmd.Connection.Close();  
}

protected void Button2_Click(object sender, EventArgs e) 
{ 
     string  comm="insert into login values(@val1,@val2)";         
    con = new SqlConnection();         
    con.ConnectionString = ConfigurationManager.ConnectionStrings["con"].ConnectionString.ToString();         
    cmd = new SqlCommand(comm, con);         
    cmd.Connection.Open();

    cmd.Parameters.Add("@val1",TextBox1.Text); //Replace TextBox1.Text with your first textbox
    cmd.Parameters.Add("@val2",TextBox2.Text); //Replace TextBox2.Text with your second textbox         

    con.Open();         
    int i = cmd.ExecuteNonQuery();         
    cmd.Connection.Close();      
}
