Copy part of a string to another string in C#

Question

I'm trying to copy part of the text from text box to another string. For example if my textbox contain 10 characters, I want to copy from character 3 to character 7 to another string call TEST. How do we do it?

Accepted Answer

```
// when textbox contains "ABCDEFGHIJ", the result will be "CDEFG"
string result = textBox.Text.Substring(2, 5);
```

Keep in mind that this will throw an exception for strings shorter than 7 characters, so you may want to add some length checks.
