我正在开发 asp.net Web 应用程序。我正在通过 lists.asmx Web 服务访问共享点列表数据。同样，我通过lists.asmx 在sharepoint 列表中添加数据。我添加新列表项的代码如下

public void InsertDataInClientList(Client clientObj)
        {
            PBSWebApplication.LocalHostServiceReference.ListsSoapClient proxy = Utility.GetLocalProxy();

            try
            {

                XmlDocument doc = new XmlDocument();
                XmlElement batch = doc.CreateElement("Batch");

                batch.InnerXml = "<Method ID='1' Cmd='New'>"
                    + "<Field Name='FirstName'>" + clientObj.FirstNameOfIndividual + "</Field>"
                    + "<Field Name='Last_x0020_Name'>" + clientObj.LastNameOfIndividual + "</Field>"
                    + "<Field Name='PATIENT_x0020_DOB'>" + clientObj.DateOfBirth.ToString("yyyy-MM-dd") + "</Field>"
                    + "<Field Name='Age'>" + clientObj.Age + "</Field>"

                XElement xElement = Utility.ToXElement(batch);

                proxy.UpdateListItems("Clients", xElement);
            }
            catch (Exception ex)
            {
                Utility.ShowErrorMessage(ex);
            }

        }

上面的代码工作正常。我可以添加新的列表项。在上面的代码中，“客户”列表是自定义列表。现在在“客户”列表中，我还有一个字段名为 Image。它属于“超链接或图像”类型。我可以通过提供网址手动在此列中添加图像。但我想通过后面的代码添加这个图像。我有图像的字节数组。我也有源网址。我想添加具有上述字段值的图像。我想为特定列表项添加图像。意味着我想通过添加图像来更新列表项。我该怎么做。您能否提供我可以解决上述问题的任何代码或链接？

当我使用 SharePoint 的 Web 服务创建文件时，我总是最终使用复制服务。如果您要向列表项添加附件，则可以解决此问题。如果没有，下面是一个可以让您朝着正确方向前进的示例：

    Byte[] bytes = new Byte[InputFile.PostedFile.InputStream.Length];
    InputFile.PostedFile.InputStream.Read(bytes, 0, bytes.Length);
    string soapStr =
        @"<?xml version=""1.0"" encoding=""utf-8""?>
            <soap:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
              <soap:Body>
                <CopyIntoItems xmlns=""http://schemas.microsoft.com/sharepoint/soap/"">
                  <SourceUrl>http://devint/a/ceo/PublishingImages/FridayMemoHeader1.png</SourceUrl>
                  <DestinationUrls>
                    <string>http://sp-pubdev:88/Resources/Images/testFile.png</string>
                  </DestinationUrls>
                  <Fields>
                  </Fields>
                  <Stream>{1}</Stream>
                </CopyIntoItems>
              </soap:Body>
            </soap:Envelope>";

    System.Net.HttpWebRequest req = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(Url);
    req.Headers.Add("SOAPAction", "\"http://schemas.microsoft.com/sharepoint/soap/CopyIntoItems\"");
    req.ContentType = "text/xml;charset=\"utf-8\"";
    req.Accept = "text/xml";
    req.Method = "POST";
    //req.Credentials = System.Net.CredentialCache.DefaultCredentials;
    req.Credentials = new System.Net.NetworkCredential("myUserName", "myPassword", "Domain");

    using (System.IO.Stream stm = req.GetRequestStream())
    {
        soapStr = string.Format(soapStr, "testFile.png", Convert.ToBase64String(bytes));
        using (System.IO.StreamWriter stmw = new System.IO.StreamWriter(stm))
        {
            stmw.Write(soapStr);
        }
    }

您可能对前两行最感兴趣，它们只是将文件加载到字节数组中，这一行：

soapStr = string.Format(soapStr, "testFile.png", Convert.ToBase64String(bytes));

该字节数组被转换为 base64 字符串并插入到 SOAP 请求中。祝你好运！
