winform程序压缩文件上传，服务器端asp.net mvc进行接收解压
标签：ror rman tor output tip ctf open access 添加
期间编程没什么难度，唯一可能忽略导致结果失败是asp.net mvc配置
对于压缩文件大的话，需要配置mvc的最大接收量：
winform中压缩和上传:
调用部分如下：
string proPath = Application.StartupPath + "\\temp\\product\\" + project.ProjectName;
ZipFile(proPath,proPath + ".zip");//压缩
var uploadResult = Upload_Request(WebConfig.UploadUrl + "/Mobile/ReceiveProjectFile", proPath + ".zip",
project.ProjectName + ".zip");//上传
if (uploadResult == 0)
{
LoadingForm.CloseLoadingCircle();
Notification t = new Notification("方案附件上传失败，请重试！", 3, FormAnimator.AnimationMethod.Slide, FormAnimator.AnimationDirection.Up, true, "error");
t.Show();
return;
}
File.Delete(proPath + ".zip");

/// 压缩文件路径
public void ZipFile(string strFile, string strZip)
{
if (strFile[strFile.Length - 1] != Path.DirectorySeparatorChar)
strFile += Path.DirectorySeparatorChar;
ZipOutputStream s = new ZipOutputStream(File.Create(strZip));
s.SetLevel(6); // 0 - store only to 9 - means best compression
zip(strFile, s, strFile);
s.Finish();
s.Close();
}
private void zip(string strFile, ZipOutputStream s, string staticFile)
{
if (strFile[strFile.Length - 1] != Path.DirectorySeparatorChar) strFile += Path.DirectorySeparatorChar;
Crc32 crc = new Crc32();
string[] filenames = Directory.GetFileSystemEntries(strFile);
foreach (string file in filenames)
{
if (Directory.Exists(file))
{
zip(file, s, staticFile);
}
else // 否则直接压缩文件
{
//打开压缩文件
FileStream fs = File.OpenRead(file);
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
string tempfile = file.Substring(staticFile.LastIndexOf("\\") + 1);

entry.DateTime = DateTime.Now;
entry.Size = fs.Length;
fs.Close();
crc.Reset();
crc.Update(buffer);
entry.Crc = crc.Value;

asp.net mvc接收压缩包，并解压：

//解压出来的文件保存的路径
string rootDir = " ";
//根目录下的第一个子文件夹的名称
while ((theEntry = s.GetNextEntry()) != null)
{
rootDir = Path.GetDirectoryName(theEntry.Name);
//得到根目录下的第一级子文件夹的名称
if (rootDir.IndexOf("\\") >= 0)
{

//以下为解压缩zip文件的基本步骤
//基本思路就是遍历压缩文件里的所有文件,创建一个相同的文件。
