Question

我在我的视觉C# Console Application(Visualroom 2005 .NET 2.0 Framework)中做了以下发言。

using System.Configuration;

我在申请中使用以下声明:

ConfigurationManager.AppSettings["SomeStringOverHere"];

I try to build the application and I get the error: The name ConfigurationManager does not exist in the current context.

任何帮助?

Answer 1

您需要参考系统:项目组合和“使用”说明。

姓名空间(有时)为各议会的“分层”。这意味着,单一名称空间的类型实际上存在于不同的议会中。

确定哪些组装是《联邦法典》或《联邦法典》类型,将其看管国。如果你看,请看看一下,你发现这套软件在该系统内。通过在“大会”顶部附近进行装配。这是您需要参考的项目。

Answer 2

菲利普正确地补充了这一提法,但我实际上去了并试图下载DLL,因为我不知道有较容易的方法。

right-click on add references folder in the solution explorer
select the .NET tab
search for the .NET reference you would like to add (in this case System.Configuration)

由于大家,这一职位对我非常有益。

Answer 3

at the solution explorer
select References
then click Add Reference from the right mouse button menu

in the top right corner write "Configuration:
check the System.Configuration, which would show up
press OK
