获取目录或文件的完整目录。
public:
virtual property System::String ^ FullName { System::String ^ get(); };C#
public virtual string FullName { get; }member this.FullName : stringPublic Overridable ReadOnly Property FullName As String包含完整目录的字符串。
完全限定路径名称和文件名的长度超出系统定义的最大长度。
调用方没有所要求的权限。
以下示例演示 了 FullName 属性。 此代码示例是为 FileSystemInfo 类提供的一个更大示例的一部分。
static void DisplayFileSystemInfoAttributes(FileSystemInfo^ fsi)
{
// Assume that this entry is a file.
String^ entryType = "File";
// Determine if entry is really a directory
if ((fsi->Attributes & FileAttributes::Directory) == FileAttributes::Directory)
{
entryType = "Directory";
}
// Show this entry's type, name, and creation date.
Console::WriteLine("{0} entry {1} was created on {2:D}", entryType, fsi->FullName, fsi->CreationTime);
}
C#
static void DisplayFileSystemInfoAttributes(FileSystemInfo fsi)
{
// Assume that this entry is a file.
string entryType = "File";
// Determine if entry is really a directory
if ((fsi.Attributes & FileAttributes.Directory) == FileAttributes.Directory )
{
entryType = "Directory";
}
// Show this entry's type, name, and creation date.
Console.WriteLine("{0} entry {1} was created on {2:D}", entryType, fsi.FullName, fsi.CreationTime);
}
Sub DisplayFileSystemInfoAttributes(ByVal fsi As IO.FileSystemInfo)
' Assume that this entry is a file.
Dim entryType As String = "File"
' Determine if this entry is really a directory.
If (fsi.Attributes And FileAttributes.Directory) = FileAttributes.Directory Then
entryType = "Directory"
End If
' Show this entry's type, name, and creation date.
Console.WriteLine("{0} entry {1} was created on {2:D}", _
entryType, fsi.FullName, fsi.CreationTime)
End Sub
例如，对于文件 c:\NewFile.txt，此属性返回“c:\NewFile.txt”。
