我正在尝试使用名为copy.asmx的sharepoint webservices从文档中下载文件。它的文件大小为100 kb。
但它没有下载文件。
Web服务迭代在Web服务响应中返回空流(out byte [] Stream)。是任何记忆问题。
它也像“download_document()内存不足”那样返回
注意:我正在使用MFP打印机查看此应用程序。

请尝试以下功能。您需要传递FileURL(文档的完整网址),标题(您希望为下载的文件提供通行证名称。)
public string DownLoadfiletolocal(string FileURL, string Title)
{
//Copy.Copy is a webservice object that I consumed.
Copy.Copy CopyObj = new Copy.Copy();
CopyObj.Url = SiteURL + "/_vti_bin/copy.asmx"; // Dynamically passing SiteURL
NetworkCredential nc2 = new NetworkCredential();
nc2.Domain = string.Empty;
nc2.UserName = _UserName;
nc2.Password = _Password;
string copySource = FileURL; //Pass full url for document.
Copy.FieldInformation myFieldInfo = new Copy.FieldInformation();
Copy.FieldInformation[] myFieldInfoArray = { myFieldInfo };
byte[] myByteArray;
// Call the web service
uint myGetUint = CopyObj.GetItem(copySource, out myFieldInfoArray, out myByteArray);
// Convert into Base64 String
string base64String;
base64String = Convert.ToBase64String(myByteArray, 0, myByteArray.Length);
// Convert to binary array
byte[] binaryData = Convert.FromBase64String(base64String);
// Create a temporary file to write the text of the form to
string tempFileName = Path.GetTempPath() + "\\" + Title;
// Write the file to temp folder
FileStream fs = new FileStream(tempFileName, FileMode.Create, FileAccess.ReadWrite);
fs.Write(binaryData, 0, binaryData.Length);
fs.Close();
return tempFileName;
}
