# TypeInitializationException

***

**1. Exception Handling**

```csharp
try
{
    // Code that might throw a TypeInitializationException
}
catch (TypeInitializationException ex)
{
    // Handle the exception
}
```

**2. Checking for Static Constructor Exceptions**

```csharp
Type type = typeof(MyClass);
try
{
    type.GetConstructor(Type.EmptyTypes);
}
catch (TypeInitializationException ex)
{
    // Handle the exception
}
```

**3. Debugging Static Constructor Errors**

```csharp
AppDomain.CurrentDomain.UnhandledException += (sender, args) =>
{
    if (args.ExceptionObject is TypeInitializationException)
    {
        // Handle the exception
    }
};
```

**4. Using Custom ExceptionFilterAttribute**

```csharp
[ExceptionFilter(typeof(MyExceptionFilterAttribute))]
public class MyClass
{
    public static int StaticField;
}
```

**5. Exception Handling in Static Constructors**

```csharp
public class MyClass
{
    static MyClass()
    {
        try
        {
            // Code that might throw a TypeInitializationException
        }
        catch (Exception ex)
        {
            // Handle the exception
        }
    }
}
```

**6. Using Try-Catch in Static Property Initializers**

```csharp
public class MyClass
{
    public static int StaticProperty
    {
        get
        {
            try
            {
                // Code that might throw a TypeInitializationException
            }
            catch (Exception ex)
            {
                // Handle the exception
            }

            return 0;
        }
    }
}
```

**7. Throwing TypeInitializationExceptions in Static Constructors**

```

**8. Using TypeInitializationException for Lazy Initialization**

            if (_instance == null)
            {
                lock (_padlock)
                {
                    if (_instance == null)
                        try
                        {
                            _instance = new object();
                        }
                        catch (TypeInitializationException)
                        {
                            // Handle the exception
                        }
                }
            }

            return _instance;
        }
    }
}
```

            // Code that might throw a TypeInitializationException
        }
