使用StreamReader将MemoryStream转换为字符串。

<Extension()> _
Public Function ReadAll(ByVal memStream As MemoryStream) As String
    ' Reset the stream otherwise you will just get an empty string.
    ' Remember the position so we can restore it later.
    Dim pos = memStream.Position
    memStream.Position = 0

    Dim reader As New StreamReader(memStream)
    Dim str = reader.ReadToEnd()

    ' Reset the position so that subsequent writes are correct.
    memStream.Position = pos

    Return str
End Function

只使用方法Convert。ToBase64String

Convert.ToBase64String(inputStream.ToArray());

byte[] array = Encoding.ASCII.GetBytes("MyTest1 - MyTest2");
MemoryStream streamItem = new MemoryStream(array);

// convert to string
StreamReader reader = new StreamReader(streamItem);
string text = reader.ReadToEnd();

我需要集成一个类，需要一个流写在它:

XmlSchema schema;
// ... Use "schema" ...

var ret = "";

using (var ms = new MemoryStream())
{
    schema.Write(ms);
    ret = Encoding.ASCII.GetString(ms.ToArray());
}
//here you can use "ret"
// 6 Lines of code

我创建了一个简单的类，可以帮助减少多次使用的代码行:

public static class MemoryStreamStringWrapper
{
    public static string Write(Action<MemoryStream> action)
    {
        var ret = "";
        using (var ms = new MemoryStream())
        {
            action(ms);
            ret = Encoding.ASCII.GetString(ms.ToArray());
        }

        return ret;
    }
}

然后可以用一行代码替换示例

var ret = MemoryStreamStringWrapper.Write(schema.Write);

使用StreamReader将MemoryStream转换为字符串。

<Extension()> _
Public Function ReadAll(ByVal memStream As MemoryStream) As String
    ' Reset the stream otherwise you will just get an empty string.
    ' Remember the position so we can restore it later.
    Dim pos = memStream.Position
    memStream.Position = 0

    Dim reader As New StreamReader(memStream)
    Dim str = reader.ReadToEnd()

    ' Reset the position so that subsequent writes are correct.
    memStream.Position = pos

    Return str
End Function

使用StreamReader，然后你可以使用ReadToEnd方法返回一个字符串。
