示例
以下示例打开或创建文件，确定其完整路径，并确定并显示目录的完整内容。
using namespace System;
using namespace System::IO;
int main()
{
// Open an existing file, or create a new one.
FileInfo^ fi = gcnew FileInfo( "temp.txt" );
// Determine the full path of the file just created.
DirectoryInfo^ di = fi->Directory;
// Figure out what other entries are in that directory.
array<FileSystemInfo^>^fsi = di->GetFileSystemInfos();
Console::WriteLine( "The directory '{0}' contains the following files and directories:", di->FullName );
// Print the names of all the files and subdirectories of that directory.
Collections::IEnumerator^ myEnum = fsi->GetEnumerator();
while ( myEnum->MoveNext() )
{
FileSystemInfo^ info = safe_cast<FileSystemInfo^>(myEnum->Current);
Console::WriteLine( info->Name );
}
}
