  • Question

  • Hi,

    I want to know that how to move a zipentry to different location.

    If i take a example..

    foreach (ZipEntry e in zip)
                            {
                                if (e.IsDirectory == false && (e.FileName.Contains("CalData") == false) && (e.FileName.Contains("_") == true))
                                {
                                    string[] fileFetch = e.FileName.Split('/');
                                    string fileFetchEx = fileFetch[0] + "\\" + fileFetch[2];
                                    
                                    if ((fileFetch[2].Contains("CalData") == false) && (fileFetch[2].Contains("_") == true))
                                    {
                                        System.Data.Linq.ISingleResult<ShopBatchTransactionDetail> sp = db.ShopBatchTransactionDetailReadByFile(stagingLocation + fileFetchEx);
    
                                        int count = (from t in db.ShopBatchTransactionDetailReadByFile(stagingLocation + fileFetchEx)
                                                     select t).Count();
    
                                        if (count > 0)
                                        {
                                            db.ShopBatchTransactionDetailUpdate(shopBatchTransactionDetailId, skippedStatus, user);
                                        }
                                        else
                                        {
                                            //foreach (ShopBatchTransactionDetail entry in sp)
                                            //{
                                            //if (entry.FilePath != (stagingLocation + fileFetchEx))
                                            //{
                                            try
                                            {
                                                string shopFolder = fileFetch[0].Substring(0, 3);
                                                string finalPath = shopFolder + "/" + fileFetch[2];
                                                e.FileName = finalPath;
                                                e.Extract(stagingLocation, ExtractExistingFileAction.OverwriteSilently);
                                                e.FileName = fileFetch[0] + "/" + fileFetch[1] + "/" + fileFetch[2];

    As shown on my above code, I removed one folder from ZipEntry e,

    as it was e.FileName = "Folder1/Folder2/File1.txt" and i modified it to

    e.FileName = "Folder1/File1.txt", that is what i needed.

    But then in my code i got below error.

    "Collection was modified; enumeration operation may not execute."

    Please help me in this.

  • Hi Dynamic,

    Welcome to the MSDN Forum.

    This is by design. You cannot modified the collection foreach statement is enumerating.

    When you need to change the element during the enumeration, please use for or while, both them have no such limitation.

    I hope this will be helpful.

    Best regards,
