A potentially dangerous Request.Form value was detected from the client (ContentBody_txtContent="<style type="text/cs...").

.aspx新增了<%@ Page validateRequest="false"%>

最後找到還需要在web.config裡面新增<httpRuntime requestValidationMode="2.0" />

若你的 Web 應用程式真的會傳遞超過 1,000 個欄位時，這個預設值也是可以設定的，請修改網站根目錄下的 web.config 檔，並在 區段加上一組 aspnet:MaxHttpCollectionKeys 設定即可：

<appSettings>

 <add key="aspnet:MaxHttpCollectionKeys" value="2500" />

</appSettings>
