我在我的mvc asp.net项目中使用DevExpress控件.这是代码：
<div>
@Html.DevExpress().TextBox(settings =>
{
settings.Name = "TextBox";
settings.Width = 170;
settings.Properties.DisplayFormatString = "[ 00 - 00 - 00 ]";
settings.Text = "123456";
}).GetHtml()
</div>
这是错误信息：
Unable to cast the object type "System.Web.Mvc.HtmlHelper` 1 [System.Object]" to type "System.Web.Mvc.HtmlHelper"
解决方法
Ty for link,Nitin Varpe.我将此部分添加到我的主web.config：
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="4.0.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
