How can I convert String to Int in C#?

http://stackoverflow.com/questions/1019793/how-can-i-convert-string-to-int

Try this:

int x = Int32.Parse(TextBoxD1.Text);

or better yet:

int x = 0;

Int32.TryParse(TextBoxD1.Text, out x);

Also, since

Int32.TryParse

returns
a

bool

you
can its return value to make decisions about the results of the parsing attempt:

int x = 0;

if (Int32.TryParse(TextBoxD1.Text, out x))
{
// you know that the parsing attempt
// was successful
}

If you are curious, the difference between

Parse

and

TryParse

is
best summed up like this:

The TryParse method is like the Parse method, except the TryParse method does not throw an exception if the conversion fails. It eliminates the need to use exception handling to test for a FormatException in the event that s is invalid and cannot be successfully
parsed. - MSDN
