Crystal报告SetDataSource中的错误

Question

我在VS 2010 sap crystalreports中遇到麻烦,使用c#制作一个Windows应用程序.

我使用以下代码得到以下错误:

 CrystalReport1 cr1 = new CrystalReport1();
 cr1.SetDataSource(dt1); //Error 

Could not load file or assembly 'file:///C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win64_x64\dotnet1\crdb_adoplus.dll' or one of its dependencies. The system cannot find the file specified.

Answer 1

尝试通过将useLegacyV2RuntimeActivationPolicy属性添加到.config文件来使用此解决方案

<startup useLegacyV2RuntimeActivationPolicy="true">

Answer 2

 <startup useLegacyV2RuntimeActivationPolicy="true" >
    <supportedruntime version="v4.0" sku=".NETFramework,Version=v4.0" />
 </startup>

在app.config中添加此代码.
