链接异常是一系列处理异常的try-catch语句。要创建异常链，即链接异常−
设置第一个try-catch −
static void Main(string[] args) {
try {
One();
} catch (Exception e) {
Console.WriteLine(e);
}
}现在在方法One()下尝试使用try-catch −
static void One() {
try {
Two();
} catch (Exception e) {
throw new Exception("First exception!", e);
}
}方法Two()还会继续链式异常。
static void Two() {
try {
Three();
} catch (Exception e) {
throw new Exception("Second Exception!", e);
}
}现在是下一个方法。
static void Three() {
try {
Last();
} catch (Exception e) {
throw new Exception("Third Exception!", e);
}
}The takes us to the last.
static void Last() {
throw new Exception("Last exception!");
}在运行上述代码时，异常会被处理如下 −
System.Exception: First exception! ---< System.Exception: Middle Exception! ---< System.Exception: Last exception! at Demo.Two () [0x00000] in <199744cb72714131b4f5995ddd1a021f>:0 --- End of inner exception stack trace --- at Demo.Two () [0x00016] in <199744cb72714131b4f5995ddd1a021f>:0 at Demo.One () [0x00000] in <199744cb72714131b4f5995ddd1a021f>:0 --- End of inner exception stack trace --- at Demo.One () [0x00016] in <199744cb72714131b4f5995ddd1a021f>:0 at Demo.Main (System.String[] args) [0x00000] in <199744cb72714131b4f5995ddd1a021f>:0
