(C#) Zip Files in a Date RangeSee more Zip ExamplesDemonstrates how to use the Zip.MinDate and Zip.MaxDate properties to zip only those files with a last-modified date within a date range. Note: This example requires Chilkat v10.0.0 or greater.
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. bool success; Chilkat.Zip zip = new Chilkat.Zip(); string zipPath = "c:/temp/qa_output/out.zip"; // Initialize the zip object with the path of the .zip to be created. zip.NewZip(zipPath); // The MinDate and MaxDate properties use the timestamp date/time string format. // Here are some examples: // YYYY-MM-DD (e.g., 2024-07-31) // YYYY-MM-DDTHH:MM:SS�HH:MM (e.g., 2024-07-31T12:34:56+02:00) // 2024-07-31T12:34:56Z (the "Z" denotes Zulu time, or UTC) // Only append files having a last-modified date greater than 1-Jan-2017 zip.MinDate = "2017-01-01T00:00:00Z"; // Also, only append files having a last-modified date less than the end of 2020 zip.MaxDate = "2020-12-31T23:59:59Z"; // You don't need to specify both MinDate and MaxDate. // You can specify only one or the other if needed. // The MinDate/MaxDate properties apply to all of the Chilkat methods for appending files. // Recursively append to the zip object the paths of the files and directories in a directory tree. // At this point we are not creating the .zip, nor are we reading the contents of the files. // We are simply appending references to the files and directories in the local filesystem // that will get processed when WriteZip is called. bool recurse = true; success = zip.AppendFiles("c:/temp/files_to_zip",recurse); if (success == false) { Debug.WriteLine(zip.LastErrorText); return; } zip.FileName = zipPath; success = zip.WriteZip(); if (success == false) { Debug.WriteLine(zip.LastErrorText); return; } zip.CloseZip(); Debug.WriteLine("Success"); |
