Question

我最近在我网站的某个页面中遇到此错误。

这种例外的原因是什么？任何想法如何解决？

Answer 1

是的。当ASP.NET系统收到请求，将其路由到您的处理程序并且ModelBinder接管传递给处理程序中的参数的映射值时，会发生此错误。当其中一个parms是一个字符串并且该字符串已启动但未终止时，它将从System.String.DeserializeString（）方法抛出System.ArgumentException。

您有两种选择。

在发送之前，使用JavaScript在浏览器中修复字符串数据。（杜）。
创建自定义Model Binder以优雅地处理异常并发回500系列HTTP错误或更好，然后以可预测的方式修复数据。这种修复并不总是像声音文件，图像，电影或其他base64编码的blob一样。

以下是＃2 - Creating a custom model binder的方法。

ArgumentException：传入未终止的字符串
