C#WinForm APP.CONFIG配置文件的操作

取值代码:首先添加应用,System.configuration

string serverName = System.Configuration.ConfigurationManager.AppSettings["serverName"];

string serverIp = System.Configuration.ConfigurationManager.AppSettings["serverIp"];

动态修改或者添加信息到配置文件中代码:

private void frmTransfer_FormClosing(object sender, FormClosingEventArgs e)

{

string jobSaveValue = txtSavePath.Text.Trim();

string tempLateValue = txtSaveTempLate.Text.Trim();

SaveConfig(jobSaveValue,tempLateValue);

}

private void SaveConfig(string jobSaveValue,string tempLateValue)

{

string jobSave = "jobSavePath";

string tempLate = "templateSavePath";

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

List<string> keys = new List<string>(config.AppSettings.Settings.AllKeys);

if (keys.Contains(jobSave))

{

config.AppSettings.Settings[jobSave].Value = jobSaveValue;

}

else

{

config.AppSettings.Settings.Add(jobSave , jobSaveValue);

}

if (keys.Contains(tempLate))

{

config.AppSettings.Settings[tempLate].Value = tempLateValue;

}

else

{

config.AppSettings.Settings.Add(tempLate,tempLateValue);

}

config.Save();

System.Configuration.ConfigurationManager.RefreshSection("appSettings");

}
