==Exception Translation: CLR catches an exception and rethrows a different exception. The inner exception contains the original exception.==

<source lang="csharp">
using System;
using System.Reflection;

public class MyClass {
public static void MethodA() {
Console.WriteLine("MyClass.MethodA");
throw new Exception("MethodA exception");
}
}
public class Starter {
public static void Main() {
try {
Type zType = typeof(MyClass);
MethodInfo method = zType.GetMethod("MethodA");
method.Invoke(null, null);
} catch (Exception except) {
Console.WriteLine(except.Message);
Console.WriteLine("original: " + except.InnerException.Message);
}
}
}
</source>

==Throw and catch Exception==

<source lang="csharp">
using System;
class ExceptionThrower {
static void MethodOne() {
try {
MethodTwo();
} finally { }
}
static void MethodTwo() {
throw new Exception("Exception Thrown in Method Two");
}
public static void Main(String[] args) {
try {
ExceptionThrower FooBar = new ExceptionThrower();
MethodOne();
} catch (Exception e) {
Console.WriteLine(e.Message);
} finally {
// Cleanup code
}
}
}
</source>

==Throw exception from getter==

<source lang="csharp">
using System;
public class MyValue {
public String Name;
}
class CardDeck {
private MyValue[] Cards = new MyValue[52];
public MyValue GetCard(int idx) {
if ((idx >= 0) && (idx <= 51))
return Cards[idx];
else
throw new IndexOutOfRangeException("Invalid Card");
}
public static void Main(String[] args) {
try {
CardDeck PokerDeck = new CardDeck();
MyValue HiddenAce = PokerDeck.GetCard(53);
} catch (IndexOutOfRangeException e) {
Console.WriteLine(e.Message);
} catch (Exception e) {
Console.WriteLine(e.Message);
} finally {
// Cleanup code
}
}
}
</source>
