LoadFromStream error

[emamanu_1987]

hi,
i'm using this method,

Code: Select all

document.LoadFromStream(stream, Spire.Doc.FileFormat.Docx);

in this case working fine:

Code: Select all

MemoryStream stream = new MemoryStream(value);       
Spire.Doc.Document document = new Spire.Doc.Document();
document.LoadFromStream(stream, Spire.Doc.FileFormat.Docx);

but if i try this, exception System.Xml.XmlException: ''':

Code: Select all

string s = System.Text.Encoding.Unicode.GetString(value, 0, (value).Length);
byte[] ba = Encoding.Unicode.GetBytes(s);
MemoryStream stream = new MemoryStream(ba);       
Spire.Doc.Document document = new Spire.Doc.Document();
document.LoadFromStream(stream, Spire.Doc.FileFormat.Docx);

i checked the leght of both byte array and they are sames.
what i wrong?

Hello,

Thanks for your inquiry.
Kindly note that the byte array after Unicode encoding may be different from the byte array obtained by directly reading the file. To compare whether the two byte arrays are completely consistent, you can verify it through the following code. In any case, we do not recommend customers to load files after encoding. If you have other questions, please feel free to write back.

Code: Select all

byte[] streamData = File.ReadAllBytes("in.docx");
// Convert the byte array to a Unicode-encoded string
string s = System.Text.Encoding.Unicode.GetString(streamData, 0, streamData.Length);
// Convert the string back to a Unicode-encoded byte array
byte[] stream1Data = Encoding.Unicode.GetBytes(s);
if (!streamData.SequenceEqual(stream1Data))
{
    Console.WriteLine("The two MemoryStream objects contain different data.");

    // Find the first different byte position
    int firstDifferentIndex = -1;
    for (int i = 0; i < Math.Min(streamData.Length, stream1Data.Length); i++)
    {
        if (streamData[i] != stream1Data[i])
        {
            firstDifferentIndex = i;
            break;
        }
    }
    if (firstDifferentIndex != -1)
    {
        Console.WriteLine($"The first different byte is at index {firstDifferentIndex}:");
        Console.WriteLine($"stream data: 0x{streamData[firstDifferentIndex]:X2}");
        Console.WriteLine($"stream1 data: 0x{stream1Data[firstDifferentIndex]:X2}");
    }
    else
    {
        // If the lengths are different, print the length difference
        Console.WriteLine($"The two MemoryStream objects have different lengths. " +
                          $"stream length: {streamData.Length}, stream1 length: {stream1Data.Length}");
    }
}
else
{
    Console.WriteLine("The two MemoryStream objects contain the same data.");
}

thank you.
i solved using base64 conversion.
