无法找到类型或命名空间名称“CrystalDecisions”（您是否缺少using指令或程序集引用 [英] type or namespace name 'CrystalDecisions' could not be found (are you missing a using directive or an assembly reference

问题描述

我在创建Crystal Report并构建项目时收到错误消息。错误消息是：

I am getting an error message when I create my Crystal Report and build the project. The error message is:

"type or namespace name 'CrystalDecisions' could not be found (are you missing a using directive or an assembly reference?"

我看到一些针对Targeted Framework的回复应该是
.net Framework 4 client profile，但是没有解决问题。



我使用Visual Studio 2010和Crystal Reports内置菜单选项，我的项目中有以下参考：

I have seen some responses that Targeted Framework should be
".net Framework 4 client profile", but that did not solve the problem.

I am using Visual Studio 2010 with Crystal Reports built in menu option and I have the following references in my project:

using CrystalDecisions.Shared;
using CrystalDecisions.ReportSource;
using CrystalDecisions.CrystalReports.Engine;

当我创建.rpt文件时，带有using语句的代码是为我构建的，所以我不知道它为什么会出现问题。



有谁知道为什么会这样？

The code with the using statements is built for me when I create the .rpt file, so I don''t know why it is having a problem.

Does anyone know why this is happening?

我遇到了同样的问题，这就是我所做的。我转到我的项目的属性，并选择.NET Framework 4作为目标框架而不是.NET Framework 4 Client Profile。之后我重建了我的项目并且工作正常。

I had the same problem and this is what I did. I went to the properties of my project and chose .NET Framework 4 as the target Framework instead of .NET Framework 4 Client Profile. I rebuild my project afterwards and it worked.
