好的,我可以帮你解决这个问题。首先,你需要引入 DotNetZip 库,然后按照以下步骤进行操作:
1. 创建一个 ZipOutputStream 对象,并设置压缩文件名和密码:
```
ZipOutputStream zipStream = new ZipOutputStream(File.Create("压缩文件名.zip"));
zipStream.Password = "密码";
```
2. 创建一个 ZipEntry 对象,并设置文件名:
```
ZipEntry entry = new ZipEntry("文件名");
```
3. 将 ZipEntry 对象添加到 ZipOutputStream 对象中:
```
zipStream.PutNextEntry(entry);
```
4. 将文件流写入 ZipOutputStream 对象中:
```
byte[] buffer = new byte[4096];
int bytesRead;
while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) > 0)
{
zipStream.Write(buffer, 0, bytesRead);
}
```
5. 关闭 ZipEntry 和 ZipOutputStream 对象:
```
zipStream.CloseEntry();
zipStream.Close();
```
这样就可以将文件流转成带密码的压缩文件了。完整代码示例:
```
using (FileStream fileStream = new FileStream("文件路径", FileMode.Open))
{
using (ZipOutputStream zipStream = new ZipOutputStream(File.Create("压缩文件名.zip")))
{
zipStream.Password = "密码";
ZipEntry entry = new ZipEntry("文件名");
zipStream.PutNextEntry(entry);
byte[] buffer = new byte[4096];
int bytesRead;
while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) > 0)
{
zipStream.Write(buffer, 0, bytesRead);
}
zipStream.CloseEntry();
zipStream.Close();
}
}
```
