C#获取当前程序运行路径的几种方法标题)

1. 获取模块的完整路径。

string path = System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName;
Debug.Print(path);

输出：C:\Users\Lenovo\Desktop\QRCode\QRCode\bin\Debug\QRCode.vshost.exe

2. 获取和设置当前目录(该进程从中启动的目录)的完全限定目录

string path = System.Environment.CurrentDirectory;
Debug.Print(path);

输出：C:\Users\Lenovo\Desktop\QRCode\QRCode\bin\Debug

3. 获取应用程序的当前工作目录

string path = System.IO.Directory.GetCurrentDirectory();
Debug.Print(path);

输出：C:\Users\Lenovo\Desktop\QRCode\QRCode\bin\Debug

4. 获取程序的基目录

string path = System.AppDomain.CurrentDomain.BaseDirectory;
Debug.Print(path);

输出：C:\Users\Lenovo\Desktop\QRCode\QRCode\bin\Debug\

5. 获取和设置包括该应用程序的目录的名称

string path = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase;
Debug.Print(path);

输出：C:\Users\Lenovo\Desktop\QRCode\QRCode\bin\Debug\

6. 获取启动了应用程序的可执行文件的路径

string path = System.Windows.Forms.Application.StartupPath;
Debug.Print(path);

输出：C:\Users\Lenovo\Desktop\QRCode\QRCode\bin\Debug

7. 获取启动了应用程序的可执行文件的路径及文件名

string path = System.Windows.Forms.Application.ExecutablePath;
Debug.Print(path);

输出：C:\Users\Lenovo\Desktop\QRCode\QRCode\bin\Debug\QRCode.EXE

e.g：

string path1 = System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName;
string path2 = System.Environment.CurrentDirectory;
string path3 = System.IO.Directory.GetCurrentDirectory();
string path4 = System.AppDomain.CurrentDomain.BaseDirectory;
string path5 = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase;
string path6 = System.Windows.Forms.Application.StartupPath;
string path7 = System.Windows.Forms.Application.ExecutablePath;
StringBuilder str = new StringBuilder();//拼接字符串输出
str.Append("System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName:" + path1);
str.Append("System.Environment.CurrentDirectory:" + path2);
str.Append("System.IO.Directory.GetCurrentDirectory():" + path3);
str.Append("System.AppDomain.CurrentDomain.BaseDirectory:" + path4);
str.Append("System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase:" + path5);
str.Append("System.Windows.Forms.Application.StartupPath:" + path6);
str.Append("System.Windows.Forms.Application.ExecutablePath:" + path7);
string allPath = str.ToString();
Debug.Print(allPath);

输出运行结果：
1.System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName:
C:\Users\Lenovo\Desktop\QRCode\QRCode\bin\Debug\QRCode.vshost.exe
2.System.Environment.CurrentDirectory:
C:\Users\Lenovo\Desktop\QRCode\QRCode\bin\Debug
3.System.IO.Directory.GetCurrentDirectory():
C:\Users\Lenovo\Desktop\QRCode\QRCode\bin\Debug
4.System.AppDomain.CurrentDomain.BaseDirectory:
C:\Users\Lenovo\Desktop\QRCode\QRCode\bin\Debug
5.System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase:
C:\Users\Lenovo\Desktop\QRCode\QRCode\bin\Debug
6.System.Windows.Forms.Application.StartupPath:
C:\Users\Lenovo\Desktop\QRCode\QRCode\bin\Debug
7.System.Windows.Forms.Application.ExecutablePath:
C:\Users\Lenovo\Desktop\QRCode\QRCode\bin\Debug\QRCode.EXE
