如何以编程方式从InfoPath XSN模板创建InfoPath表单 [英] How to programmatically create an InfoPath form from an InfoPath XSN template

问题描述

我需要一个从SharePoint服务器上存在的XSN模板创建InfoPath实例表单的解决方案，我正在使用

I need a solution that creates an InfoPath instance form from an XSN template that exists on a SharePoint server, I am using this approach but this extracts template files on temp directory of server that we may not have write permission to. Is there better solution for this?

推荐答案

您只需将CAB库更改为可以将模板文件提取到内存的库，就像这样，

You just change the CAB-library, to one that can extract the template file to memory, as this one,

从内存中的.CAB存档或InfoPath XSN文件中提取的最少C#代码

然后调用myCab.ExtractFile("template.xml", out buffer, out bufferLen);

完整的代码看起来像

private byte[] GetXmlForm(SPDocumentLibrary list) {
  byte[] data = null;
  SPFile file = list.ParentWeb.GetFile(list.DocumentTemplateUrl);


  Stream fs = file.OpenBinaryStream();
  try {
    data = new byte[fs.Length];
    fs.Read(data, 0, data.Length);
  } finally {
    fs.Close();
  }

  byte[] buffer;
  int bufferLen;  
  CabExtract cab = new CabExtract(data);
  cab.ExtractFile("template.xml", out buffer, out bufferLen);

  return buffer;
}
