Sharepoint 2013 PDF与元数据字段 [英] Sharepoint 2013 PDF with metadata fields

问题描述

我正在运行sharepoint 2013基金会，并希望制作内容类型为pdf。我想映射到PDF本身的sharepoint元数据字段，但我无法找到使用adobe acrobat dc的任何方法。有没有人这样做，可以给b
指示如何做到这一点？

我的目标是，如果用户创建新文档，她将会看到pdf表单，她填充和sharepoint列将被填充。

My goal is that if a user creates new document she will be presented with the pdf form which she fills and the sharepoint columns would be filled.

推荐答案

我们可以创建一个事件接收者实现它。

We can create an event receiver to achieve it.

1。使用GacUtil.exe，在GAC中安装iTextSharp.dll。

1. Using the GacUtil.exe, install the iTextSharp.dll in the GAC.

2。创建一个名为"元数据"的新列。并使其成为"多线"类型。

2. Create a new column called "Metadata" and make it a "Multiline" type.

3。为文档库创建一个事件接收器。

3. Create an event receiver for document library.

4。在事件接收器ItemAdded方法中，将下面的代码添加到此方法中。

4. In event receiver ItemAdded method, add the code below to this method.

base.ItemAdded(properties);
SPFile f = properties.ListItem.File;
SPListItem currentItem = properties.ListItem;
if (f.Name.EndsWith(".pdf"))
{
	byte[] pdfIn = f.OpenBinary();
	PdfReader pr = new PdfReader(pdfIn);
	string meta = "";
	foreach (KeyValuePair<string, string> pair in pr.Info)
	{
		meta = meta + pair.Key + " = " + pair.Value + ";";
	}
	currentItem["Metadata"] = meta;
	currentItem.SystemUpdate();
}

5。对于ItemUpdating事件，添加以下代码行：

5. For the ItemUpdating event add the following lines of code:

base.ItemUpdating(properties);
properties.ListItem["Metadata"] = properties.AfterProperties["Metadata"];
