I don't know what do you mean by converting a stream to a string. Also what's the other side?
我不知道将流转换为字符串是什么意思。还有另一面是什么？
In order to convert a stream to a string you need to use an encoding. Here's an example of how this could be done if we suppose that the stream represents UTF-8 encoded bytes:
为了将流转换为字符串，您需要使用编码。如果我们假设流表示 UTF-8 编码的字节，这是一个如何完成的示例：
using (var reader = new StreamReader(foo.UploadStream, Encoding.UTF8))
{
string value = reader.ReadToEnd();
// Do something with the value
}

After some searching , other answers to this question suggest you can do this without knowing / using the string's encoding . Since a stream is just bytes , those solutions are limited at best . This solution considers the encoding:
经过一番搜索，此问题的其他答案表明您可以在不知道/使用字符串的 encoding 的情况下执行此操作。由于流只是字节，因此这些解决方案充其量是有限的。此解决方案考虑了编码：
public static String ToEncodedString(this Stream stream, Encoding enc = null)
{
enc = enc ?? Encoding.UTF8;
byte[] bytes = new byte[stream.Length];
stream.Position = 0;
stream.Read(bytes, 0, (int)stream.Length);
string data = enc.GetString(bytes);
return enc.GetString(bytes);
}
