在MVC 5 (asp.net Identity)中，GeneratePasswordToken抛出了一个奇怪的错误——

Question

我使用下面的代码创建一个LostPassword函数。当用户输入他们的电子邮件时，他们会得到一个包含重置令牌链接的密码。在我的控制器中，我有GenerateTokenPassword方法(在WebSecurity下)，但它抛出了这个错误:

错误:无法将类型"string"转换为"int"行:var token = WebSecurity.GeneratePasswordResetToken((foundUserName).ToString()， 1440);

当我调试时，我在foundUserName字段中得到我的用户名，它是一个字符串。1440是令牌过期时的超时，我将提供一个int作为开始。它看起来像什么?

你知道这是什么吗?

谢谢,

它会出现编译器将1440值解释为字符串，您可以尝试为它声明一个显式的int变量并传递它。

或者，假设tokenExpirationInMinutesFromNow是一个可选参数，默认已经是1440，那么您可以完全省略它

var token = WebSecurity.GeneratePasswordResetToken((foundUserName).ToString());
