从同一解决方案中的单独类库中访问Web.Config [英] Access Web.Config from a seperate Class Library in same Solution

问题描述

所以我有这个层次结构：


+解决方案

|

| --- +类库项目

| |

| | --- LogError.vb

|

| --- + ASP .NET Web应用程序

|

| --- Web.config


我想从Web.config访问：


< appSettings>

< add key =" sqlConnString"来自LogError.vb的$ = $ b< / appSettings>


.value =" myDBString">
有人知道我会怎么做吗？

So I have this hierarchy:

+ Solution
|
|--- + Class Library Project
| |
| |--- LogError.vb
|
|--- + ASP .NET Web Application
|
|--- Web.config

I want to access from Web.config:

<appSettings>
<add key="sqlConnString" value="myDBString">
</appSettings>

from LogError.vb. Anyone know how I would go about doing this?

推荐答案

首先，我的理解是这种事情不是允许。


其次，我很好奇你为什么要这样做。


最后，web.config只是一个文本文件如果你需要阅读内容，你就可以这样对待它。但;不要期望使用web.config文件配置您的

类库项目。创建一个新的配置文件

或者，使用machine.config文件

First of all, it is my understanding that this sort of thing is not allowed.

Second, I am curious on why you want to do this.

Lastly, the web.config is just a text file and you can treat it as such if
you just need to read the contents. But; don''t expect to configure your
class library project using the web.config file. Create a new config file
Or, use the machine.config file

嗨布拉德。

如果你想阅读二进制web.config文件你将需要使用

Server.MapPath方法。

Dim reader As New System.IO.StreamReader（Server.MapPath（" web。） config"））

Dim value As String = reader.ReadToEnd


如果你想读取web.config部分内的值appSettings只是

使用ConfigurationSetting命名空间


Dim sqlConStr As String =

ConfigurationSettings.AppSettings（" sqlConnString"）

Hi Brad.
If you want to read the binary web.config file you will need to use the
Server.MapPath methods.

Dim reader As New System.IO.StreamReader(Server.MapPath("web.config" ))
Dim value As String = reader.ReadToEnd

If you want to read the value inside the web.config section appSettings just
use the ConfigurationSetting namespace

Dim sqlConStr As String =
ConfigurationSettings.AppSettings("sqlConnString")

我构建了一个应用程序来记录和查看我们的所有错误和错误

应用程序有。我们在许多

应用程序中使用了一个通用的类库项目。 LogError函数位于其中一个类库中。在

命令存储错误的应用程序ID我需要访问Web.config文件中的

应用程序ID键。


Tampa.NET Koder写道：

I built an Application to log and view all the errors and bugs our
applications have. We use a common Class Library Project in many of our
applications. The LogError function is in one of these Class Libraries. In
order to store the Application ID of the error I need to access the
Application ID key in the Web.config file.
