Question

我将对象序列化为JSON。我想在ZIP中压缩它。 ZIP文件已创建，但结果显示已损坏且为空。如果你能说出来，我将非常感激。

public void Write(List<Dictionary<string,string>> data)
{
    if (data.Count == 0) // If the collection is empty, then return
        return;
    PartNumber++; // In the archive are added many files. This is part of a single file
    string FullFileName = FolderWrite + FileName + ".zip";
    fsWrite = new FileStream(FullFileName, FileMode.OpenOrCreate, FileAccess.ReadWrite);
    ZipArchive archive = new  ZipArchive(fsWrite, ZipArchiveMode.Update);
    ZipArchiveEntry entry = archive.CreateEntry(FileName + ".part_" + PartNumber.ToString(), CompressionLevel.Optimal);
    Stream s = entry.Open();
    DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(List<Dictionary<string,string>>));
    ser.WriteObject(s, data);
    s.Close();
    fsWrite.Close();
}

需要

archive.Dispose();

结果

public void Write(List<Dictionary<string,string>> data)
        {

            if (data.Count == 0)
                return;
            PartNumber++;
            string FullFileName = FolderWrite + FileName + ".zip";
            ZipArchive archive;

            fsWrite = new FileStream(FullFileName, FileMode.OpenOrCreate, FileAccess.ReadWrite);

            archive = new  ZipArchive(fsWrite, ZipArchiveMode.Update);

            ZipArchiveEntry entry = archive.CreateEntry(FileName + ".part_" + PartNumber.ToString(), CompressionLevel.Optimal);
            Stream s = entry.Open();
            DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(List<Dictionary<string,string>>));
            ser.WriteObject(s, data);
            archive.Dispose();
            s.Close();
            fsWrite.Close();
        }
    }
