最近研究了两种PDF文件查看器，MoonPdfLib或者AdobeReader。

今天先说第一种，在网上扒到的很好的WPF中用MoonPdf类库来展示PDF文件。

在Sourceforge上下载到MoonPdf编译好的Dll。

https://github.com/reliak/moonpdf这是源码地址。

使用非常简单，废话不多说，上码上步骤。

1、程中添加对MoonPdfLib.dll的引用。注意：将libmupdf.dll放置于WPF工程Bin文件下。

2、XMAL源码：

3、C#代码：

private bool _isLoaded = false;
public MainWindow()
{
InitializeComponent(); //数据库要存放的路径
string filePath = "\\File\\ExceptionHandlingVSTO.pdf";
//获取文件名字
string fileName = Path.GetFileName(filePath); TreeModel loc = new TreeModel()
{
Name = "施工前",
Childern = new List<TreeModel>()
{
new TreeModel()
{
Name = fileName,
FilePath = filePath
},
new TreeModel()
{
Name ="测试节点可以无视",
FilePath = filePath
}
}
};
List<TreeModel> list = new List<TreeModel>() { loc };
treeView.ItemsSource = list; }
private void FileButton_Click(object sender, RoutedEventArgs e)
{
form.OpenFileDialog dialog = new form.OpenFileDialog();
dialog.Multiselect = true;
if (dialog.ShowDialog() == form.DialogResult.OK)
{
string[] filesPath = dialog.FileNames; if (filesPath != null && filesPath.Length > )
{
foreach (var filePath in filesPath)
{
Upload(filePath);
}
}
}
}
/// <summary>
/// 文件上传
/// </summary>
/// <param name="filePath">文件原来的路径</param>
public void Upload(string filePath)
{
try
{
FileInfo info = new FileInfo(filePath); string directory = Directory.GetCurrentDirectory();
string uploadFile = $"{directory}\\File";
//文件要上传的路径
string uploadPath = $"{uploadFile}\\{info.Name}"; WebClient wc = new WebClient();
//wc.Credentials = new NetworkCredential("xuyue", "111111");
FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read);
BinaryReader br = new BinaryReader(fs);
byte[] result = br.ReadBytes(Convert.ToInt32(fs.Length));
Stream s = wc.OpenWrite(new Uri(uploadPath), "PUT"); if (s.CanWrite)
{
s.Write(result, , result.Length);
}
s.Flush();
s.Close();
fs.Close(); }
catch (Exception ex)
{
throw ex;
} } private void ZoomInButton_Click(object sender, RoutedEventArgs e)
{
if (_isLoaded)
{
moonPdfPanel.ZoomIn();
}
} private void ZoomOutButton_Click(object sender, RoutedEventArgs e)
{
if (_isLoaded)
{
moonPdfPanel.ZoomOut();
}
} private void NormalButton_Click(object sender, RoutedEventArgs e)
{
if (_isLoaded)
{
moonPdfPanel.Zoom(1.0);
}
} private void FitToHeightButton_Click(object sender, RoutedEventArgs e)
{
moonPdfPanel.ZoomToHeight();
} private void FacingButton_Click(object sender, RoutedEventArgs e)
{
moonPdfPanel.ViewType = MoonPdfLib.ViewType.Facing;
} private void SinglePageButton_Click(object sender, RoutedEventArgs e)
{
moonPdfPanel.ViewType = MoonPdfLib.ViewType.SinglePage;
} private void treeView_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e)
{
//数据库要存放的路径
string fileName = "\\File\\ExceptionHandlingVSTO.pdf";
string filePath = $"{Directory.GetCurrentDirectory()}{fileName}"; try
{
moonPdfPanel.OpenFile(filePath);
_isLoaded = true;
}
catch (Exception ex)
{
_isLoaded = false;
}
}
}
