How to convert nullable int to string

Question

I need to convert the nullable int to string ``` int? a = null; string str = a.ToString(); ``` How can I perform this action without an exception? I need to get the string as "Null". Please guide me.

Accepted Answer

You can simply use the `Convert.ToString()` which handles the null values as well and doesn't throw the exception

```
string str = Convert.ToString(a)
```

Or using `if` condition

```
if(a.HasValue)
{
  string str = a.Value.ToString();
}
```

Or using `?` Ternary operator

```
string str = a.HasValue ? a.Value.ToString() : string.Empty;
```
