Question

我正在使用带有C＃的VS2010开发SharePoint 2010应用程序，我需要一个代码将文件从共享文档复制到本地文件夹。

我写了这段代码：

var dest = @"C:\location";
var source = @"http://server1/sites/PrDB/";
var fileName = "sql.txt";

using (SPSite site = new SPSite(source))
{
    using (SPWeb web = site.OpenWeb())
    {
            SPFile file = web.GetFile("Shared%20Documents/" + fileName);
            byte[] b = file.OpenBinary();
            FileStream fs = new FileStream(dest + "\\" + file.Name, FileMode.Create, FileAccess.ReadWrite);
            BinaryWriter bw = new BinaryWriter(fs);
            bw.Write(b);
            bw.Close();
    }
}

我收到了一行错误：file.OpenBinary（）;

无法打开文件“Shared Documents / sql.txt”。

有人知道为什么吗？我该如何解决？

要获取文件，您需要传递完整的URL。请尝试以下代码：

  var dest = @"C:\location";
    var source = @"http://server1/sites/PrDB/";
    var fileName = "sql.txt";

    using (SPSite site = new SPSite(source))
    {
        using (SPWeb web = site.OpenWeb())
        {
                SPFile file = web.GetFile(web.Url +"/Shared%20Documents/" + fileName);// here, this added web url
    if(file.Exists) 
        {
                byte[] b = file.OpenBinary();
                FileStream fs = new FileStream(dest + "\\" + file.Name, FileMode.Create, FileAccess.ReadWrite);
                BinaryWriter bw = new BinaryWriter(fs);
                bw.Write(b);
                bw.Close();
        }
    }
 }

我知道您正在寻找基于代码的解决方案。但如果您愿意选择OOTB解决方案，那么只需将一行代码附加到锚标记的href

UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Game Over" message:@"Your time is up" preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *close = [UIAlertAction actionWithTitle:@"close" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {
                                                                 **exit(0);**
                                                             }];
UIAlertAction *playagain = [UIAlertAction actionWithTitle:@"Play again" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {
                                                                  [self viewDidLoad];
                                                             }];

[alert addAction:close];
[alert addAction:playagain];

[self presentViewController:alert animated:YES completion:nil];

我在尝试数小时后找到了解决方案，问题在于使用SPWeb读取文件：

    var dest = @"C:\location";
    var source = @"http://server1/sites/PrDB/";
    using (SPSite site = new SPSite(source))
         {
              using (SPWeb web = site.OpenWeb())
              {
                    SPFolder myfolder = web.GetFolder("Shared Documents");
                    SPFile file = myfolder.Files[fileName];
                    byte[] b = file.OpenBinary();
                    string fullPath =destination + "\\" + file.Name;
                    FileStream fs = new FileStream(fullPath, FileMode.Create, FileAccess.ReadWrite);
                    BinaryWriter bw = new BinaryWriter(fs);
                    bw.Write(b);
                    bw.Close();
                    }
                }
