sharpziplib +提取單個文件

Question

每當我嘗試獲取文件時，輸入流（s.Length）的長度始終爲零，我做錯了什麼？的ZipEntry是有效的並且具有的文件的正確的大小等

下面是使用代碼IM：

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; 
} 

Answer 1

輸入流將不具有的長度。改爲使用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; 
}
