在某些情况下,如何处理类似于以下类的所有异常？

class Test : IDisposable {
  public Test() {
    throw new Exception("Exception in ctor");  
  }
  public void Dispose() {
    throw new Exception("Exception in Dispose()");
  }
  ~Test() {
    this.Dispose();
  }
}

我试过这个,但它不起作用:

static void Main() {
  Test t = null;
  try {
    t = new Test();
  }
  catch (Exception ex) {
    Console.Error.WriteLine(ex.Message);
  }

  // t is still null
}

我也尝试使用"使用"但它不处理从~Test()抛出的异常;

static void Main() {
  try {
    using (Test t = new Test()) { }
  }
  catch (Exception ex) {
    Console.Error.WriteLine(ex.Message);
  } …

我在Windows 7(64位)上设置VS 2008 SP1并尝试构建psutil,出现以下错误.VS 2008已正确设置并且SP1已成功修补.

我根据包中的INSTALL文件运行了"python setup.py build"命令.
