PDF文件不會顯示在列表視圖c＃2008

Question

我嘗試在Listview中顯示PDF文件爲LargeIcon。但它不顯示。

我可以顯示所有圖像格式。

如何在ListView中顯示PDF文件？

我試過這樣，只是像圖像顯示。

private void import(string path) 
{ 

    ListView1.Items.Clear(); 
    ImageList imageList = new ImageList(); 
    imageList.Images.Clear(); 
    imageList.ImageSize = new Size(170, 140); 
    imageList.ColorDepth = ColorDepth.Depth32Bit; 

    int i = 0; 

    ////ArrayList to hold the files with the certain extensions 
    ArrayList files1 = new ArrayList(); 

    if (Directory.Exists(path).Equals(true)) 
    { 
     string validExtensions = "*.pdf"; 

     //create a string array of our filters by plitting the 
     //string of valid filters on the delimiter 
     string[] extFilter = validExtensions.Split(new char[] { ',' }); 

     //loop through each extension in the filter 
     foreach (string extension in extFilter) 
     { 
      files1.AddRange(Directory.GetFiles(path, extension)); 
      files = (string[])files1.ToArray(typeof(String)); 
     } 

     string[] pathes = new string[files.Length]; 

     foreach (string file in files) 
     { 
      pathes[i] = file; 
      i++; 
     } 

     foreach (string path1 in pathes) 
     { 
      imageList.Images.Add(Bitmap.FromFile(path1)); 
      FileInfo fileInfo = new FileInfo(path1); 
      String strDir = fileInfo.Name; 
      ListView1.Items.Add(strDir); 
      ListView1.TileSize = new System.Drawing.Size(100, 80); 
     } 
     for (int j = 0; j < pathes.Length; j++) 
     {     
      this.ListView1.Items[j].ImageIndex = j; 
     } 

     this.ListView1.View = View.LargeIcon; 
     this.ListView1.LargeImageList = imageList; 

     ListView1.Focus(); 
     ListView1.Items[0].Selected = true; 
     } 
    } 
} 

Answer 1

您需要找到.Net PDF渲染器。

請參閱this question。

Answer 2

您將需要柵格化PDF。我認爲ImageMagick（也許與Ghostscript結合）可以做到這一點。

工作中，我們點生成PDF一個.NET庫，在這裏獲得的映像：
