如何在.net中更改Application.exe.config文件的位置 [英] How to change the location of the Application.exe.config file in .net
问题描述
在vb.net/C#中是否可以更改 application.exe.config
文件的位置?
Is it possible in vb.net/C# to change where the application.exe.config
file is located?
这不是这个问题,正如您在我的代码中看到的那样,我已经尝试过此方法,但它对我不起作用。
This is not a duplicate of this question, as you can see in my code I tried this method already, it didn't work for me.
Public Class Form1
Public Sub New()
Try
'Two Methods to change the path of the application.exe.config file i tried, both dont work
AppDomain.CurrentDomain.SetData("APP_CONFIG_FILE", "C:\Temp\AppConfig.exe.config")
Dim config As Configuration = ConfigurationManager.OpenExeConfiguration("C:\Temp\AppConfig.exe.config")
InitializeComponent()
'EntityFramework ---------------------------
Dim db = New WfpModel 'DbContext --> MyBase.New("name=ConnectionMSSQL")
gridWFP.DataSource = db.ADR.ToList()
gridWFP.Refresh()
'WebService ---------------------------
Dim Client = New Netlogistik.ServiceClient
Dim filter = New TRANSPORT_FILTER With {.ID = 0}
gridNet.DataSource = Client.WfpNetTransport("myUserName", "myPassword", filter.GetTransportFilter)?.Tables("OUT")
gridNet.Refresh()
Catch ex As Exception
'EntityFramework Result: System.InvalidOperationException:
' "No connection string named ConnectionMSSQL was found in the application configuration file."
'
'WebService Result: No default endpoint element was found that references the Netlogistic.IService
' contract in the ServiceModel client configuration section.
' This could be due to the following reasons: No configuration file was found for the application,
' Or no endpoint element matching the contract was found in the client element.
MsgBox(ex.Message)
End Try
End Sub...
推荐答案
由于行为是由.NET Framework内部管理的,因此无法更改应用程序配置文件的位置。
You can't change the app config file location since the behavior is managed by the .NET Framework internally.
但是您可以使用手工制作的单例类创建自己的配置文件并管理参数,该类可以以xml或二进制格式序列化到要放置的位置。
But you can create your own configuration file and manage parameters with a hand-made singleton class that can be serialized in xml or binary format where you want to put it.
示例:
using System.Xml.Serialization;
[Serializable]
public class AppSettings
{
// The singleton
static public AppSettings Instance { get; private set; }
static public string Filename { get; set; }
static AppSettings()
{
Instance = new AppSettings();
}
// The persistence
static public void Load()
{
if ( !File.Exists(Filename) )
return;
using ( FileStream fs = new FileStream(Filename, FileMode.Open, FileAccess.Read) )
Instance = (AppSettings)new XmlSerializer(typeof(AppSettings)).Deserialize(fs);
}
static public void Save()
{
using ( FileStream fs = new FileStream(Filename, FileMode.Create, FileAccess.Write) )
new XmlSerializer(Instance.GetType()).Serialize(fs, Instance);
}
// The settings
public bool IsFirstStartup { get; set; } = true;
public string ExportPath { get; set; }
}
测试:
static void Test()
{
AppSettings.Filename = "c:\\Test\\AppSettings.xml";
AppSettings.Load();
if ( AppSettings.Instance.IsFirstStartup )
{
AppSettings.Instance.IsFirstStartup = false;
AppSettings.Instance.ExportPath = "c:\\Test\\Export";
AppSettings.Save();
Console.WriteLine("App initialized.");
}
else
{
Console.WriteLine("Welcome back.");
}
}
它需要添加 System项目文件中的.Runtime.Serialization
程序集引用。
It needs to add System.Runtime.Serialization
assembly reference in the project file.
