C# 获得根路径

asp.net:

System.Web.HttpContext.Current.Server.MapPath("~/App_Data/tmp/");

winform:

System.AppDomain.CurrentDomain.BaseDirectory + "\\App_Data\\tmp\\";

AppDomain.CurrentDomain.RelativeSearchPath

if (HttpContext.Current == null)
{
    serverLogPath = AppDomain.CurrentDomain.BaseDirectory + "\\App_Data\\tmp\\";
}
else
{
    serverLogPath = HttpContext.Current.Server.MapPath("~/App_Data/tmp/");
}

获取当前运行程序

windows app的执行路径AppDomain.CurrentDomain.BaseDirectory

asp.net的执行路径AppDomain.CurrentDomain.SetupInformation.PrivateBinPath或者AppDomain.CurrentDomain.RelativeSearchPath

后者获取回来是带有“bin”文件夹在后面的

ASP.NET MVC测试

System.Environment.CurrentDirectory // E:\\GZ\\GZBlog\\YESCMS
System.AppDomain.CurrentDomain.BaseDirectory // E:\GZ\GZBlog\YESCMS\bin\Debug\net5.0\
System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase // E:\GZ\GZBlog\YESCMS\bin\Debug\net5.0\
AppDomain.CurrentDomain.RelativeSearchPath // null
