            using (var sWriter = new StreamWriter(destPath)) {

答

您可以使用 WebRequest 来完成此任务，以便从 Sharepoint 站点下载文件:

you can achieve this task using WebRequest in order to download files from sharepoint site:

public void DownloadFile(string serverFilePath, string destPath)
{
    var url = string.Format("{0}/{1}", ServerURL, serverFilePath);
    Directory.CreateDirectory(Path.GetDirectoryName(destPath)); // this method creates your directory
    var request = System.Net.HttpWebRequest.Create(url);
    request.Credentials = System.Net.CredentialCache.DefaultCredentials;
    using (var sReader = new StreamReader(request.GetResponse().GetResponseStream()))
    {
        using (var sWriter = new StreamWriter(destPath))
        {
            sWriter.Write(sReader.ReadToEnd());
        }
    }
}

如果您希望使用 Client-object-model，请阅读:如何使用 SharePoint 客户端对象模型获取一个只有绝对 url 的文件?

if you wish to use the Client-object-model you read that: How to get a file using SharePoint Client Object Model with only an absolute url at hand?
