使用 IEnumerable<Exception> 自己的异常

Question

我想自己做个例外，比如AggregateException：

var exceptions = ErrorCollectionExtension.GetErrorsAsExceptions(compiler.Errors);

throw new AggregateException("Error", exceptions);

可以作为参数List：Exceptions

public MyException(string message, IEnumerable<Exception> innerExceptions)

        : base(message, innerExceptions)

    {

    }

innerExceptions但是我在 base上遇到错误。

如何通过收集它来制作自己的例外AggregateException？

一种方法是Exception通过一组内部异常来简单地扩展类，有点像这样：public class MyException : Exception{&nbsp; &nbsp; private readonly ReadOnlyCollection<Exception> _innerExceptions;&nbsp; &nbsp; public MyException(string message, IEnumerable<Exception> innerExceptions)&nbsp; &nbsp; &nbsp; &nbsp; : base(message, innerExceptions.FirstOrDefault())&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; _innerExceptions = innerExceptions.ToList().AsReadOnly();&nbsp; &nbsp; }&nbsp; &nbsp; public ReadOnlyCollection<Exception> InnerExceptions => _innerExceptions;}或者你可以继承AggregateException并使用它的结构：public class MyException : AggregateException{&nbsp; &nbsp; public MyException(string message, IEnumerable<Exception> innerExceptions)&nbsp; &nbsp; &nbsp; &nbsp; : base(message, innerExceptions)&nbsp; &nbsp; {&nbsp; &nbsp; }}
