public
void
saveValue(
string
Name,
string
Value)
{
ConfigurationManager.AppSettings.Set(Name, Value);
Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);
config.AppSettings.Settings[Name].Value = Value;
config.Save(ConfigurationSaveMode.Modified);
config =
null
;
}
用上面的函数总是等到程序运行结束，才将数据保存进去。
所以我们换了一种方式，以xml的方式进行保存及读取。直接上代码。

使用方式
设置
SetAppConfig("SourceDBIP", txtSourceAddress.Text.Trim());
读取
Setting.GetAppConfig("SourceDBIP")
