环境变量： 一边程序在下次启动的时候 可以读取上次启动的时候的配置项。（这样就可以避免使用ini，xml的配置文件了）
IDictionary environment = Environment.GetEnvironmentVariables(EnvironmentVariableTarget.User);
Environment.SetEnvironmentVariable("PMB_CONNSTRS", conns, EnvironmentVariableTarget.Machine);

ComboBox Editing, Sorting, Grouping ListView

下面这套组件 要收费，不过可以对xlsx 进行导入到一个空间中并显示等等功能：ComponentOne Studio for WPF。
EPPlus这个工具是免费的，可以对xlsx进行读取，不需要额外的组件。
