よう皆、

Crystal Reports for Visual Studio 2010 – Complete Package (EXE) を http://www.sdn.sap.com/irj/sdn/crystalreports-dotnet にインストールします。

参考にさせていただきます、
CrystalDecisions.CrystalReports.Engine
CrystalDecisions.ReportSource
CrystalDecisions.Shared
CrystalDecisions.Windows.Forms
CrystalDecisions.VSDesigner の

C:\Program Files\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86\dotnet\

次に、プロジェクトに CrystalReport2.rpt を追加します。 しかし、私は非常に多くのエラーが発生しました。

リンク 2[^]

リンク 3[^]

リンク 4[^]

それでも問題が解決しない場合は、お知らせください。

解決策 8

抜群のシェア! これだけ転送しました
これについて少し宿題をしていた同僚に。
そして、私が彼のために朝食を見つけたので、彼は実際に私に朝食を注文しました…
笑。 だから私はこれを言い換えさせてください….食事をありがとう! でもええ、使ってくれてありがとう
あなたのウェブサイトでこの問題について話し合う時間です。 ゴゾ休暇

解決策 5

これを試して

By Ahmed Omer のように、framework をクライアント バージョンではなく 4.0 に設定します。

また、プラットフォームを 64 ビットまたは 32 ビットに設定します。

解決策 3

こんにちは。

これを試して

フレームワークをクライアント バージョンではなく 4.0 に設定します。 また、プラットフォームを Any ではなく X86 または X64 に設定します。

ありがとう
