使用C＃WPF在按钮单击事件中使用文本框值更新SQL条目

Question

I have a WPF form with a button.

There is a textbox under the button and I want the .text to go into a list box

The syntax for your update command should be something like this, note that you haven't mentioned the name of the table in the database which is storing the data, so I've just called it ButtonTable :

...
cmd.CommandText = "UPDATE [ButtonTable] SET [TimesClicked] = @nm WHERE [ButtonName] = @buttonName;";
cmd.Parameters.Add("@buttonName", SqlDbType.VarChar, 100).Value = "Button1";
cmd.Parameters.Add("@nm", SqlDbType.Int).Value = textBox1.Text;
...

Also, I recommend specifying the type of your parameters as in the above sample.
