winform获取app.config的helper

winform获取app.config的helper

核心代码：

ConfigurationManager.ConnectionStrings["name"].ConnectionString;

把这个类搞进去，每次调用带上name就行

using System.Configuration;

namespace he.Tool
{
    public class ConfigHelper
    {
        public string GetAppConfigByName(string name)
        {
            return ConfigurationManager.ConnectionStrings[name].ConnectionString;
        }
    }
}
