推荐答案

您输入的路径是相对路径.Windows CE/Mobile 不支持相对路径.

The path you you have typed it is a relative path. Windows CE/Mobile does not support relative paths.

因此，由于在 Windows Mobile 设备上没有当前目录的概念，如何定位仅知道相对路径的资源?.Net 程序始终可以访问组成它的模块(通常一个 .Net 组件由一个打包在 DLL 或 EXE 文件中的模块组成).以下行将返回当前正在执行的程序集的绝对路径.

It follows that since there is no concept of a current directory on a Windows Mobile device how would one locate a resource for which only a relative path is known? A .Net program always has access to the modules of which it is composed (usually a .Net component is composed of one module packaged in a DLL or EXE file). The following line will return the absolute path to the currently executing assembly.

string modulePath = this.GetType().Assembly.GetModules()[0].FullyQualifiedName;

string modulePath = this.GetType().Assembly.GetModules()[0].FullyQualifiedName;

多一点代码你就可以得到你的程序运行的目录

with a little more code you can get the directory in which your program is running

Path.GetDirectoryName(this.GetType().Assembly.GetModules()[0].FullyQualifiedName)

Path.GetDirectoryName(this.GetType().Assembly.GetModules()[0].FullyQualifiedName)

使用该信息，您可以为您的资源构建正确的路径字符串.

Using that information you can build a proper path string to your resource.

注意:如果您使用本机 APIS 进行开发，请使用以下内容:GetModuleFileName(GetModuleHandle(NULL), pszFullPath, MAX_PATH);

note: If you are developing using the native APIS use the following: GetModuleFileName(GetModuleHandle(NULL), pszFullPath, MAX_PATH);
