我试着谷歌搜索了解它,但找到了同样错误的不同答案让我更加困惑.
Exception caught in Global.asax:System.Web.HttpRequestValidationException (0x80004005): A potentially dangerous Request.Form value was detected from the client (ctl00$MainContent$WarningCtl1$TXTWarningText=”

请建议.
解决方法
[ValidateInput (false)]
public class MyController : Controller { ... }
或者你的行动方法：
public class MyOtherController : Controller
{
[ValidateInput (false)]
public ActionResult MyActionMethod (MyObjectThatTakesInHtml myObject)
{ ... }
}
编辑
正如@dotjoe指出的那样,我忘了提及,您还可以访问模型中属性的AllowHtmlAttribute(在System.Web.Mvc中找到).
public class MyObjectThatTakesInHtml
{
[AllowHtml]
public string MyHtmlProperty { get; set; }
}
