C# (CSharp) FileSystemNodesComparer示例

示例#1

    public void TestSortingFileAndDirectory(bool isAscending, SortingMode sortingColumn)
    {
        _autoMocker.Use(true);

        var directoryViewModel = _autoMocker.CreateInstance <DirectoryViewModel>();

        var comparer = new FileSystemNodesComparer(isAscending, sortingColumn);

        var result = comparer.Compare(directoryViewModel, fileViewModel);

        Assert.True(result < 0);

        result = comparer.Compare(fileViewModel, directoryViewModel);
        Assert.True(result > 0);
    }

示例#2

            result = comparer.Compare(directoryViewModel, parentDirectoryViewModel);
            Assert.True(result > 0);
        }
