This is probably a silly and very easy question but how do you use a result from a query in a if statement. I am querying a table and if the result has a certain value I want it to carry out a function.
Code so far:

C#

private void ButtonLogin_Click(object sender, RoutedEventArgs e)
{
    string connectionSQL = @"server=xxxxxxxxxxx;user id=xxxxxxxxxxxx;password=xxxxxxxx;database=xxxxxxxx";
    MySqlConnection cs = new MySqlConnection(connectionSQL);
    cs.Open();
    
    DataSet ds = new DataSet();
    
    MySqlDataAdapter da = new MySqlDataAdapter("Select username, password, type from Admin", cs);
    
    MySqlCommandBuilder cmd = new MySqlCommandBuilder(da);
    
    da.Fill(ds);
}

I want to do a if statement on values in ds in column type.

You get your result, iterate through the result, check for your condition in the if statement, if the condition is met call your function.

Are you using traditional ADO.Net or entity framework ?

Have you tried ds.tables[]["columnType"] ?

Now you can use your DataSet ds.

if you use indexes like table 0 and row 0:

C#

string user = ds.Tables[0].Rows[0];
string pass = ds.Tables[0].Rows[1];

or you can use names of the tables and rows:

C#

string user = ds.Tables["MyTableName"].Rows["Username"];
string pass = ds.Tables["MyTableName"].Rows["Password"];

Good luck,
Edo
