Question

我有一堆InfoPath表单模板（xsn），我想以编程方式上传到SharePoint列表。我的程序必须根据预定义的逻辑将这些表单模板上传到不同的列表。当我使用我的代码上传启用浏览器的表单模板（xsn）时，表单不起作用：

/// <summary>
/// Uploads a file to the specified sharepoint list
/// </summary>
/// <param name="listName"></param>
/// <param name="fileInfo"></param>
/// <param name="listVersion"></param>
/// <returns></returns>
public static bool UploadFile(string listName, FileInfo fileInfo, string listVersion)
{
    WebRequest request = WebRequest.Create(fileInfo.URL);
    request.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
    request.Method = "PUT";
    byte[] buffer = new byte[1024];
    using (Stream stream = request.GetRequestStream())
    {
        using (MemoryStream ms = new MemoryStream(fileInfo.Bytes))
        {
            for (int i = ms.Read(buffer, 0, buffer.Length); i > 0; i = ms.Read(buffer, 0, buffer.Length))
                stream.Write(buffer, 0, i);
        }
    }
    WebResponse response = request.GetResponse();
    response.Close();

    var client = new Lists.ListsSoapClient();
    var batch = new XElement("Batch",
        new XAttribute("OnError", "Continue"),
        new XAttribute("ListVersion", listVersion),
        new XAttribute("PreCalc", "TRUE"));

    var method = new XElement("Method",
        new XAttribute("ID", "1"),
        new XAttribute("Cmd", "Update"),
        new XElement("Field",
            new XAttribute("Name", "ID")),
        new XElement("Field",
            new XAttribute("Name", "FileRef"),
            fileInfo.URL));

    foreach (string key in fileInfo.Properties.Keys)
    {
        object value = fileInfo.Properties[key];

        method.Add(new XElement("Field",
            new XAttribute("Name", key),
            fileInfo.Properties[key]));
    }
    batch.Add(method);

    var element = client.UpdateListItems(listName, batch);

    var code = element.Elements().First().Elements().First().Value;
    if (code != "0x00000000")
        throw new Exception(code);
    return true;
}

似乎还有更多工作要做，只需将文件流推送到列表中即可。

任何人都知道如何做到这一点？

编辑更具体地说，我收到的错误消息是：This form template is not enabled for viewing in the browser.

更新当我使用Microsoft InfoPath发布相同的表单时，它可以正常工作。

您可以使用此代码将已上传的表单转换为启用浏览器的表单：

FormsService localFormsService;
SPFarm localFarm = SPFarm.Local;
SPSite localSite = new SPSite("http://ServerName");
SPWeb localWeb = localSite.AllWebs["SiteName"];
try
{
    localFormsService = localFarm.Services.GetValue<FormsService>(FormsService.ServiceName);
    SPFile localFile = localWeb.GetFile("FormLibrary/Forms/FormTemplate.xsn");
    localFormsService.BrowserEnableUserFormTemplate(localFile);
    Console.Write("Press Enter to Continue");
    Console.ReadLine();
}
catch (Exception ex)
{
    Console.WriteLine("Error: " + ex.Message);
    Console.Write("Press Enter to Continue");
    Console.ReadLine();
}
