OrFileComparer Class

The OrFileComparer class can be used for the Upload and Download operations. The following example code demonstrates how to use the OrFileComparer class to create a logical OR comparer from two file comparers.

...

using (Ftp client = new Ftp())
{
    // Connect to the FTP server. 
    client.Connect(MyFtpServer, MyFtpPort);

    // Authenticate. 
    client.Authenticate("test", "test");

    // Create a new instance of the TransferOptions. 
    TransferOptions opt = new TransferOptions();

    // Set transfer options 
    // Upload files with different modification date time and different file size. 
    // Files with the same size OR modification date time will not be uploaded. 
    opt.Comparer = FileComparers.FileLastWriteTimeComparer | FileComparers.FileSizeComparer; // Equivalent to 'new OrFileComparer(FileComparers.FileLastWriteTimeComparer, FileComparers.FileSizeComparer)' 
    opt.FileOverwriteMode = FileOverwriteMode.CustomCompare; // Indicates that the above Comparer is used. 
 
    // Upload files and subdirectories in "C:\test" to the current remote directory. 
    client.Upload(
        "c:\\test", // Source directory path 
        "", // Destination directory path - "" means current directory
