我正在尝试使用多个文本文件创建ZIP存档,如下所示：
Dictionary<string,string> Values = new Dictionary<string,string>();
using (var memoryStream = new MemoryStream())
{
string zip = @"C:\Temp\ZipFile.zip";
foreach (var item in Values)
{
using (var archive = new ZipArchive(memoryStream,ZipArchiveMode.Create,true))
{
var file = archive.CreateEntry(item.Key + ".txt");
using (var entryStream = file.Open())
using (var streamWriter = new StreamWriter(entryStream))
{
streamWriter.Write(item.Value);
}
}
}
using (var fileStream = new FileStream(zip,FileMode.Create))
{
memoryStream.Seek(0,SeekOrigin.Begin);
memoryStream.CopyTo(fileStream);
}
}
但是,ZIP仅使用最后一个文本文件创建,出了什么问题？
解决方法
您正在每次迭代时创建ZipArchive.交换foreach和使用应该解决它：
Dictionary<string,string>();
using (var memoryStream = new MemoryStream())
{
string zip = @"C:\Temp\ZipFile.zip";
using (var archive = new ZipArchive(memoryStream,true))
{
foreach (var item in Values)
{
var file = archive.CreateEntry(item.Key + ".txt");
using (var entryStream = file.Open())
using (var streamWriter = new StreamWriter(entryStream))
{
streamWriter.Write(item.Value);
}
}
}
using (var fileStream = new FileStream(zip,SeekOrigin.Begin);
memoryStream.CopyTo(fileStream);
}
}
