示例

以下示例演示了该 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);
}

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
