下載所有電子表格到Excel中使用C＃

Question

一個谷歌帳戶，這是我到目前爲止有：

// calls a new service and authenticate 
SpreadsheetsService myService = new SpreadsheetsService("MyDownloader"); 
myService.setUserCredentials(DownloaderSettings.Default.Username, 
    DownloaderSettings.Default.Password); 

// get a list of spreadsheets 
SpreadsheetQuery query = new SpreadsheetQuery(); 
SpreadsheetFeed feed = myService.Query(query); 

// download them all 
foreach (SpreadsheetEntry entry in feed.Entries) 
{ 
    string key = entry.AlternateUri 
         .Content 
         .Substring(entry.AlternateUri.Content.IndexOf("?key=")); 
    string dlUrl = "https://docs.google.com/feeds/download/spreadsheets/Export" 
        + key 
        + "&exportFormat=" + DownloaderSettings.Default.FileFormat 
        + "&format=" + DownloaderSettings.Default.FileFormat; 

    Stream stream = myService.Query(new Uri(dlUrl)); 

    using (FileStream fstream = new FileStream(entry.Title.ToString() + "." 
      + DownloaderSettings.Default.FileFormat), 
      FileMode.Create, 
      FileAccess.ReadWrite, 
      FileShare.ReadWrite)) 
    { 
     stream.CopyTo(fstream); 
     fstream.Flush(); 
    } 
} 

我想所有的電子表格列表在我的帳戶，並將它們全部下載到xlsx。我的帳戶中有大約10個電子表格。當我點擊調試時它們不會被創建。

Answer 1

也許這expresion ..

entry.Title.ToString() + "." + DownloaderSettings.Default.FileFormat 

不產生有效的文件名？它可能包含無效符號或類似

Answer 2

按照Mauricio Gracia的建議，我發現一些表名具有非法字符。這對我有效。

Stream stream = myService.Query(new Uri(dlUrl)); 

// declare the file name, replacing invalid characters 
string fileName = entry.Title.Text; 
string regexSearch = new string(Path.GetInvalidFileNameChars()) + new string(Path.GetInvalidPathChars()); 
Regex r = new Regex(string.Format("[{0}]", Regex.Escape(regexSearch))); 
fileName = r.Replace(fileName, "_"); 

using (FileStream fstream = new FileStream(fileName + "." + DownloaderSettings.Default.FileFormat, 
    FileMode.Create, 
    FileAccess.ReadWrite, 
    FileShare.ReadWrite)) 
{ 
    stream.CopyTo(fstream); 
    fstream.Flush(); 
}
