很怪的一个异常，高手请教

DataTable dt = BLL.ProductStockBLL.GetList();
DataList1.DataSource = dt;
DataList1.DataBind();
“BLL.ProductStockBLL”的类型初始值设定项引发异常。
在 System.TypeInitializationException 中第一次偶然出现的“App_Web_uhkycll8.dll”类型的异常

重启电脑,删掉WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\你的项目文件夹试试

[flyerwing]

试把索引服务去掉。
给临时文件夹加上权限。
我是菜鸟只会这些。
