C#操作（讀取、修改）項目exe.config文件之動態配置接口

我們經常要在項目中添加服務引用，去調用各種服務啊，接口啊。就拿調用接口來講，當你添加了服務引用後就會有一個項目congfig配置文件，裏面可以配置接口信息，像地址名稱等等，我們就可以通過修改這個congfig文件來動態調用各個接口了，當然要自己添加一個表單在界面進行修改。

先來看看這個配置了接口信息的配置文件內容：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <bindings>
            <wsHttpBinding>
                <binding name="WSHttpBinding_aaaaaaaa" messageEncoding="Mtom">
                    <security mode="None" />
                </binding>
            </wsHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://192.55.36.756:1458/Svr/HelloWorld.svc"
                binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_HelloWorld"
                contract="HelloService.HelloWorld" name="WSHttpBinding_HelloWorld" />
        </client>
    </system.serviceModel>
</configuration>

我們主要就是操作客戶端的endpoint裏的內容：

讀取操作：

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
ClientSection clientSection = config.GetSection("system.serviceModel/client") as ClientSection;
string endpointName = “Hello”;          
foreach (ChannelEndpointElement item in clientSection.Endpoints)
{       
    //判斷Endpoints節點中有沒有Name爲endpointName
    if (item.Name == endpointName) {    
        //輸出接口地址                                
        return item.Address.ToString();
    }
}

 

寫入操作：

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
ClientSection clientSection = config.GetSection("system.serviceModel/client") as ClientSection;
string endpointName = "Hello";     
string address = "http://192.32.02.163:8521/hel/Printed.svc";
foreach (ChannelEndpointElement item in clientSection.Endpoints)
{
      //是否存在endpointName           
      if (item.Name != endpointName)
          continue;
      //存在就將接口地址修改爲address
      item.Address = new Uri(address);
          break;
}
config.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("system.serviceModel");
