## Metadata{% #metadata %}

**ID:** `csharp-best-practices/use-specific-exceptions`

**Language:** C#

**Severity:** Warning

**Category:** Best Practices

## Description{% #description %}

Exceptions should be specific to the application to help points the exact issue. For these reasons, generic exceptions should not be used and we should instead favor specific exception types.

## Non-Compliant Code Examples{% #non-compliant-code-examples %}

```csharp
class MyClass {
    public static void processString(string s)
    {
        throw new Exception("foo");
        throw new ApplicationException("oh no something got wrong");
    }
}
```

## Compliant Code Examples{% #compliant-code-examples %}

```csharp
class MyClass {
    public static void processString(string s)
    {
        throw new MyCustomException("oh no!");
    }
}
```
