連結異常是一系列處理例外的try-catch語句。要建立異常鏈，即連結異常−
設定第一個try-catch −
static void Main(string[] args) {
try {
One();
} catch (Exception e) {
Console.WriteLine(e);
}
}現在在方法One()下嘗試使用try-catch −
static void One() {
try {
Two();
} catch (Exception e) {
throw new Exception("First exception!", e);
}
}方法Two()也會繼續鍊式例外。
static void Two() {
try {
Three();
} catch (Exception e) {
throw new Exception("Second Exception!", e);
}
}現在是下一個方法。
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!");
}在執行上述程式碼時，例外會被處理如下−
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
