这是System.Web.DataVisualization.dll下载，Could not load file or assembly 'System.Web.DataVisualization， Version=4.0.0.0， Culture=neutral， PublicKeyToken=31BF3856AD364E35' or one of its dependencies. The system cannot find the file specified.
System.Web.DataVisualization.dll是“System.WEB.DataVisualization， Version=3.5.0.0， Culture=neutral， PublicKeyToken=31bf3856ad364e35”或它的某一个依赖项。系统找不到指定的文件。
服务器端和客户端都安装了.NET Framework3.5SP1和Microsoft Chart Controls for Microsoft .NET Framework 3.5.exe、Microsoft .NET Framework 3.5 语言包的 Microsoft 图表控件.exe。
The primary reference "*.dll" could not be resolved because it has an indirect dependency on the framework assembly "System.Web.DataVisualization， Version=4.0.0.0， Culture=neutral， PublicKeyToken=31bf3856ad364e35" which could not be resolved in the currently targeted framework. ".NETFramework，Version=v4.0". To resolve this problem， either remove the reference "*.dll" or retarget your application to a framework version which contains "System.Web.DataVisualization， Version=4.0.0.0， Culture=neutral， PublicKeyToken=31bf3856ad364e35".
