在foreach动态调用中捕获RuntimeBinderException

Question

我有一些代码可以将JSON读取到动态对象中，如下所示：

dynamic listOfThings = JsonConvert.DeserializeObject(listOfThingsJson);

我正在像这样遍历它们：

foreach(dynamic thing in listOfThings) {
    string propertyOne = thing.PropertyOne;
    string propertyTwo = thing.PropertyTwo;
    doWork(propertyOne, propertyTwo);
}

我如何：如果在foreach语句本身或任何一个属性访问语句中遇到RuntimeBinderException，但是只是忽略该迭代的执行并继续循环，如何捕获？

类似的东西：

foreach(dynamic thing in listOfThings) { \\if a RuntimeBinderException is thrown on this line
    string propertyOne = thing.PropertyOne \\or on this line
    string propertyTwo = thing.PropertyTwo \\or on this line, catch the exception
    doWork(propertyOne, propertyTwo)      \\and move to the next iteration

Answer 1

不确定您为什么不能使用try .. catch块

foreach(dynamic thing in listOfThings) {
try {
    string propertyOne = thing.PropertyOne;
    string propertyTwo = thing.PropertyTwo;
    doWork(propertyOne, propertyTwo);
}
catch(RuntimeBinderException ex)
{
  //log the exception
  continue;
}
}
