About c # App. Config custom configuration section of the article, the Internet a lot, feel oneself should know about, but encountered a problem: generally speaking, read and write access configuration section should have two parts, but I searched the Internet for half a day, the only check how to read, to how to write,

Such as:
A, increased since the node is configured in the appconfig MySettings

 
<? The XML version="1.0" encoding="utf-8"?> 
 
 
 

 
 

 
 

 
 

 
 
 
 
 
 
 
 
 

Two, has built a management class (a prompt critical code)

 
Public static class MySettingsManager 
{
The static IDictionary MySectionDic=(IDictionary) ConfigurationManager. GetSection (" MySettings "); 
Public static string GetValue (string key) 
{
[key]. Return MySectionDic ToString (); 
} 

///& lt; Summary> 
/////modify keys 
///& lt;/summary> 
///& lt; Param name="key" & gt;  
///& lt; Param name="value" & gt;  
Public static void SetValue (string key, string value) 
{
//if there is a delete 
If (MySectionDic. The Contains (key)) {MySectionDic. Remove (key); } 

MySectionDic. Add (key, value); 
MySectionDic [key]=value; 

//WaterQuSection. Save (ConfigurationSaveMode. Modified);//this is taken for granted code should be key, seek advice, 
MySettings ConfigurationManager. RefreshSection (" "); 
} 
Public static bool KeyExists (string strKey) 
{
Foreach (string STR in MySectionDic. Keys) 
{
If (STR==strKey) 
{
return true; 
} 
} 
return false; 
} 
} 

Three, Demo debugging:
Pop-up results 0 for the first time, the second pop-up results 2, that's not a problem;
But when I opened the Appconfig view, inside AveMod Value is 0, it's a problem;
Then run again, this is the first time the pop-up result is 0, the second pop-up 2 as a result, it's a problem;

 
The static void Main (string [] args) 
{string DataBaseInfo=MySettingsManager. GetValue (" AveMod "); 
MessageBox. Show (DataBaseInfo); 

MySettingsManager. SetValue (" AveMod ", "2"); 
DataBaseInfo=MySettingsManager. GetValue (" AveMod "); 
MessageBox. Show (DataBaseInfo); 
} 

Please understand person under the guidance, giving a way...

Write must save
Or just write memory inside
RefreshSection just refresh from file

Yes, yes, all I ask is how to preserve?

WaterQuSection is IDictionary type, there is no Save method
