A string that we can change is called a StringBuilder. In this case, if we create any string object then we can perform any operation like insert, replace, etc. without creating a new instance for every time. It will update string at one place in memory doesn't create new space in memory.

Code:-

```
using System;
using System.Text;

class GFG {
   public static void Main(String[] args)
    {
        String str = "OM ";
StringBuilder sbl = new StringBuilder(str);
        sbl.Append("JI MISHRA");
        Console.WriteLine(sbl);
    }
}
```

```
Output:-OM JI MISHRA
```
