推荐答案

此问题有多种原因，您必须对其进行故障排除。



1.可能是因为你在一个不应该的目录中有一个额外的web.config。

2.它可能是因为你没有在IIS中指定一个目录作为虚拟目录。

3.可能是因为你的bin文件夹中有一个额外的dll，也许是来自不同项目的dll这也引用了ReportViewer。

4.有时你可以清除Temp ASP.Net文件夹，它会解决。



错误是说你的代码中引用的dll的两个版本之间存在冲突。

There are various reasons for this issue and it is one you'll have to troubleshoot.

1. It can be because you have an extra web.config in a directory where it shouldn't be.
2. It can be because you have not specified a directory as a virtual directory in IIS that should be one.
3. It can be because you have an extra dll in your bin folder, perhaps one from a different project that also references ReportViewer.
4. Sometimes you can clear out the Temp ASP.Net folders and it will resolve.

The error is saying you have a conflict between 2 versions of the dll being referenced in your code.

我解决了将以下版本从10更改为11及其对应的PublicKeyToken

I Solved by replaced the following version from 10 to 11 and its corresponding PublicKeyToken

<add assembly="Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />
        <add assembly="Microsoft.ReportViewer.Common, Version=10.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />

替换为

REPLACED WITH

<add assembly="Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
        <add assembly="Microsoft.ReportViewer.Common, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
