问题描述
我一直在尝试将文本框中的数据添加到名为单击按钮时注册"的数据表中.我尝试将数据添加到的列是名称".但是,当我单击按钮时,出现错误,提示我在textbox1中输入的文本(无论输入到文本框中的任何列)都不存在.我想在代码中保持相同的逻辑.任何帮助将不胜感激.
Hi I have been trying to add data from a textbox into a datatable called Registration on button click. The column I am trying to add the data to is "Name". However, when I click button, it gives me error saying the text I entered in textbox1 (whatever I entered into the textbox) column does not exist. I want to maintain the same logic in the code. Any help would be appreciated.
protected void Button1_Click(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection();
con.ConnectionString = "MY CONNECTION STRING GOES HERE";
con.Open();
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "insert into Registration (Name) values (" + Convert.ToString(TextBox2.Text) + ")";
cmd.CommandType = CommandType.Text;
cmd.Connection = con;
//cmd.ExecuteNonQuery();
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(ds);
con.Close();
}
推荐答案
如果要附加字符串数据类型,则必须使用Single quotes
.
You have to useSingle quotes
if you are appending a string datatype.
cmd.CommandText = "insert into Registration (Name) values (''" +Convert.ToString(TextBox2.Text)+ "'')";
