Question

我正在努力解决如何处理转换我的表中的System.Byte []数组来自我的Datagridview，请参阅包含仅显示Sytem.Byte []

的图像的列

这是我正在使用的代码，但它仍然只显示文本。

private void ToCsV(DataGridView DGV, string filename)

        try
        {
            if (DGV.Rows.Count != 0)
            {


                int RowCount = DGV.Rows.Count;
                int ColumnCount = DGV.Columns.Count;
                Object[,] DataArray = new object[RowCount + 1, ColumnCount + 1];

                //add rows
                int r = 0;
                for (int c = 0; c <= ColumnCount - 1; c++)
                {
                    for (r = 0; r <= RowCount - 1; r++)
                    {
                        DataArray[r, c] = DGV.Rows[r].Cells[c].Value;

Answer 1

您没有复制my answer exactly，但您错过了<GridView android:id="@+id/gridview_android_example" android:layout_width="wrap_content" ... />

ByteArrayToImage

...

Image sparePicture = ByteArrayToImage(fetch); //<-- This is what you're missing
Clipboard.SetDataObject(sparePicture);
var oPara2 = oDoc.Content.Paragraphs.Add(ref oMissing);
oPara2.Range.Paste();
oPara2.Range.InsertParagraphAfter();

你没有显示public Image ByteArrayToImage(byte[] byteArrayIn) { using (MemoryStream ms = new MemoryStream(byteArrayIn)) { Image returnImage = Image.FromStream(ms); return returnImage; } }是什么，但我假设它是fetch，所以要实现这个：

byte[]

Answer 2

先生。杰里米的想法是一个很大的帮助。我发现的缺失部分如下：

对象缺失值 - 此对象是指具有指定要放置图像的单元格的表。 [Document.Table [1] .Cells（row，col）.Range]
Image sparePicture - 而不是使用Object [，] DataArray（参见上面的代码），我使用了一个Image对象来存储图像数组，然后在剪贴板上设置并粘贴它。

InsertParagrahAfter（） - 使用此方法，我将图像逐个插入指定的单元格，就像在dataGridview中一样。

       for (int c = 0; c <= ColumnCount - 1; c++)
            {
                for (r = 0; r <= RowCount - 1; r++)
                {
                    if (c == 5)
                    {

                       Object oMissing = oDoc.Tables[1].Cell(r + 2, 6).Range; //the position where you want to put the images

                       Image sparePicture = ByteArrayToImage((byte[])DGV.Rows[r].Cells[c].Value);
                        Clipboard.SetImage(sparePicture);
                        Word.Paragraph oPara2 = oDoc.Content.Paragraphs.Add(ref oMissing);
                        oPara2.Range.Paste();
                        oPara2.Range.InsertParagraphAfter();
                    }
                }
            }

许多小时后，我创建了Encode和Serialize，这将返回一个字符串，其中包含您应用于img的src。

    string img_src = data.Rows[0].IsNull("PHOTO") ? string.Format("") : string.Format("data:image/jpeg;base64,{0}", data.Rows[0]["PHOTO"].EncodeAndSerialize().Replace("\"", ""));
----------------------------    
        public static string EncodeAndSerialize<T>(this T obj) where T : new()
                {
                    var settings = new JsonSerializerSettings
                    {
                        ContractResolver = new HtmlEncodeResolver(),
                        Formatting = Newtonsoft.Json.Formatting.None
                    };
                    return JsonConvert.SerializeObject(obj, settings);
                }
