Insert data from forms into datasets

问题

I have a dataset set up with 3 fields, ID username and password. I want the user to type in a new username and passoword and this then gets saved back to the dataset. How do I take what has been typed in and save it into the data set?

So far this is the code I have

usersTableAdapters.UsersTableAdapter user = new usersTableAdapters.UsersTableAdapter();
user.usersDataTable usertable = user.GetData();

This allows me to connect to the data set although I am not sure how to take the values the user will enter in the input boxes and save them back to the dataset?

回答1:

A quick and dirty implementation of this would look like this:

DataSet ds = new DataSet();
ds.Tables.Add(textBox1.Text);  //I did this in Winforms so, your result may vary.
ds.Tables.Add(textBox2.Text);  //Same here.

if (ds.HasChanges())  //Check if the DataSet has changes.
   ds.AcceptChanges(); //If it does, commit them.
