我最近在我网站的一个页面中遇到了这个错误。

此异常的原因可能是什么？任何想法如何解决它？

是的。当 ASP.NET 系统接收到请求，将其路由到您的处理程序并且 ModelBinder 接管以将传入的值映射到处理程序中的参数时，会发生此错误。当其中一个参数是字符串并且该字符串已启动但未终止时，它会从 System.String.DeserializeString() 方法抛出 System.ArgumentException。

你有两个选择。

  1. 在发送之前用 JavaScript 修复浏览器上的字符串数据。（呃）。
  2. 创建一个自定义模型绑定器以优雅地处理异常并发送回 500 系列 HTTP 错误，或者更好的是，以可预测的方式修复数据。这种修复并不总是可能的，就像在声音文件、图像、电影或其他 base64 编码的 blob 中一样。

以下是如何做 #2 -创建自定义模型绑定器。
