解决.Net 4.0 A potentially dangerous Request.Form value was detected from the client 异常

本文From hongshengpeng 解决ASP.NET 4.0 "A potentially dangerous Request.Form value was detected from the client". 错误在.net中,Request时出现有HTML或Javascript等字符串时,系统会认为是危险性值。立马报错。(在.aspx文件头中加入这句: <%@ Page validateRequest="false" %>,但还是出现相同错误) 或是修改web.config文件: <configuration> < system.web> <pages validateRequest="false" /> < /system.web> < /configuration> 但错误依旧。对.NET 4.0, 应该加上requestValidationMode="2.0" to the httpRuntime configuration section of the web.config :<httpRuntime requestValidationMode="2.0"/>(这句重要) 结构:<configuration> <system.web> <httpRuntime requestValidationMode="2.0">
