1.控制台应用程序
static void Main(string[] args)
{
//1.Environment.CurrentDirectory
Console.WriteLine(Environment.CurrentDirectory);
//2.AppDomain.CurrentDomain.BaseDirectory
Console.WriteLine(AppDomain.CurrentDomain.BaseDirectory);
//3.项目的目录
Console.WriteLine(Path.GetFullPath("../../"));
Console.ReadKey();
}
运行结果：
2.winform应用程序
private void Form1_Load(object sender, EventArgs e)
{
//1.Environment.CurrentDirectory
txtBox1.Text = Environment.CurrentDirectory;
//2.Application.StartupPath
txtBox2.Text = Application.StartupPath;
//3.Directory.GetCurrentDirectory()
txtBox3.Text = Directory.GetCurrentDirectory();
//4.AppDomain.CurrentDomain.BaseDirectory
txtBox4.Text = AppDomain.CurrentDomain.BaseDirectory;
}
运行结果：
3.MVC和WebForm项目
通过Server.MapPath("/")获取根目录
//WebForm
<h1><%=Server.MapPath("/") %></h1>
//Mvc
<h1>@Server.MapPath("/")</h1>
4.WebApi项目
public class ValuesController : ApiController
{
//api/values
public string Get()
{
return System.Web.Hosting.HostingEnvironment.MapPath("/");
}
}
WebApi Core的根目录获取：HttpRuntime.AppDomainAppPath
补充：WebForm /Mvc /WebApi项目的根目录为配置文件Web.config所在的目录。
