每当我尝试获取文件时,输入流的长度(s.Length)始终为零,我做错了什么? ZipEntry有效并且具有适当大小的文件等。
以下是使用的代码:
public static byte[] GetFileFromZip(string zipPath, string fileName)
{
byte[] ret = null;
ZipFile zf = new ZipFile(zipPath);
ZipEntry ze = zf.GetEntry(fileName);
if (ze != null)
{
Stream s = zf.GetInputStream(ze);
ret = new byte[s.Length];
s.Read(ret, 0, ret.Length);
}
return ret;
}
答案 0 :(得分:10)
输入流不会有长度。请改用ZipEntry.Size
。
public static byte[] GetFileFromZip(string zipPath, string fileName)
{
byte[] ret = null;
ZipFile zf = new ZipFile(zipPath);
ZipEntry ze = zf.GetEntry(fileName);
if (ze != null)
{
Stream s = zf.GetInputStream(ze);
ret = new byte[ze.Size];
s.Read(ret, 0, ret.Length);
}
return ret;
}
