try { if (CheckChanged()) { CurrenExcuse = new Excuse(random, selectedFolder); UpdateForm(false); }
} catch (SerializationException) { MessageBox.Show("You excuse file was invalid.", "Unable to open a random excuse"); }
在处理异常的时候以上代码需要在最前面增加一句
using System.Runtime.Serialization;
可以在这个网页查询到相关信息:https://msdn.microsoft.com/en-us/library/system.runtime.serialization.serializationexception(v=vs.110).aspx
