C#序列化-无效的强制转换异常
我的Windows窗体程序有一些问题。为了保存一些变量，我使用这个序列化方法。它工作得很好，但现在不知何故它不再。。。 当我运行下面的代码时，我总是得到一个无效的强制转换异常。（我将在底部发布错误消息） 问题是，实际上不应该有任何无效的演员阵容。我检查了错误消息中调用的，但是那里的转换是正确的C#序列化-无效的强制转换异常,c#,exception,serialization,casting,C#,Exception,Serialization,Casting,我的Windows窗体程序有一些问题。为了保存一些变量，我使用这个序列化方法。它工作得很好，但现在不知何故它不再。。。 当我运行下面的代码时，我总是得到一个无效的强制转换异常。（我将在底部发布错误消息） 问题是，实际上不应该有任何无效的演员阵容。我检查了错误消息中调用的，但是那里的转换是正确的 using (FileStream fs = File.Open(@"data", FileMode.Open, FileAccess.Read)) {

我真的需要一些帮助，有什么明显的我看不到的吗？听起来您的文件格式不正确，或者您丢失了一个属性。你说 对Form1.investment1=（int）（bf.反序列化（fs））的引用；这是一个正确的强制转换，因为Form1.investment1是一个整数 但是
Form1.investment1bf。反序列化（fs）intintbf.Deserialize（fs）您确定要反序列化的属性在顺序和数量上与您首先序列化以生成文件的属性匹配吗？嘿，谢谢您的回复。。。我查了一下你们的数量和订单评论，现在看来效果不错。我是这个序列化方法的新手，我不知道注释行会导致这样的问题（看起来是注释行），我保证不是注释行导致的。但也就是说，很有可能当您第二次保存文件进行测试时，它重写了一些刚才才出现的错误，而您早已忘记了这些错误。不管怎样，我很高兴它现在起作用了。我也很高兴。再次感谢！：）
