(C#) Unzip Files in a Date RangeSee more Zip ExamplesDemonstrates how to use the Zip.MinDate and Zip.MaxDate properties to unzip only those files with a last-modified date within a date range. Note: This example requires Chilkat v10.0.0 or greater.
// This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Chilkat.Zip zip = new Chilkat.Zip(); bool success = zip.OpenZip("qa_data/zips/sample.zip"); if (success != true) { Debug.WriteLine(zip.LastErrorText); return; } // 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 unzip files having a last-modified date greater than 1-Jan-2017 zip.MinDate = "2017-01-01T00:00:00Z"; // Also, only unzip 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 unzipping. int numUnzipped = zip.Unzip("c:/temp/unzipDir"); if (numUnzipped < 0) { Debug.WriteLine(zip.LastErrorText); return; } zip.CloseZip(); |
