IsolatedStorage @Windows Phone 7

Question

我已經在「汽車」文件中創建了IO 中的一些文件，我想把一些其他參考如模型，顏色等...... 所以我的問題是：是有可能有在IO 多襯裏的文件，如果是我怎樣才能在StreamReader的 讓他們//我想在一個文件中存儲的許多參數，並通過StreamReader

保護覆蓋無效找回來OnNavigatedTo（System.Windows.Navigation.NavigationEventArgs e） {

  //reception des parametres de la listbox 
      base.OnNavigatedTo(e); 
      string parameter = this.NavigationContext.QueryString["parameter"]; 
      this.tbTitre.Text = parameter; 
      try 
      { 
       //Create a new StreamReader 
       StreamReader editionDevisReader = null; 
       IsolatedStorageFile probyOrange = IsolatedStorageFile.GetUserStoreForApplication(); 
       //Read the file from the specified location. 
       editionDevisReader = new StreamReader(new IsolatedStorageFileStream("devis\\"+parameter+".txt", FileMode.Open, probyOrange)); 
       //Read the contents of the file . 
       string textFile = editionDevisReader.ReadLine(); 

       //Write the contents of the file to the TextBlock on the page. 
       tbTitre.Text = textFile; 

       while (editionDevisReader != null) 
       { 
        RowDefinition rowdefinition = new RowDefinition(); 

        TextBlock textblock = new TextBlock(); 
        textblock.HorizontalAlignment = new System.Drawing.Size(48, 20); 

       } 
       editionDevisReader.Close(); 
      } 
      catch 
      { 
       //If the file hasn't been created yet. 
       tbTitre.Text = "veuillez d abord creer le fichier"; 
      } 

THX很多都

Answer 1

是的，你可以在一個文件中保存任何東西（最高點）：

using (var store = IsolatedStorageFile.GetUserStoreForApplication()) 
{ 
    using (var isfs = new IsolatedStorageFileStream("myfile.txt", FileMode.OpenOrCreate, store)) 
    { 
     using (var sw = new StreamWriter(isfs)) 
     { 
      sw.Write("anything really. Here it's just a string but could be a serialized object, etc."); 
      sw.Close(); 
     } 
    } 
} 

然後，您可以讀取該文件：

var result = string.Empty; 

try 
{ 
    using (var store = IsolatedStorageFile.GetUserStoreForApplication()) 
    { 
     if (!store.FileExists("myfile.txt")) 
     { 
      return result; 
     } 

     using (var isfs = new IsolatedStorageFileStream("myfile.txt", FileMode.Open, store)) 
     { 
      using (var sr = new StreamReader(isfs)) 
      { 
       string lineOfData; 

       while ((lineOfData = sr.ReadLine()) != null) 
       { 
        result += lineOfData; 
       } 
      } 
     } 
    } 
} 
catch (IsolatedStorageException) 
{ 
    result = string.Empty; // may have partial data/file before error 
} 

return result;

你可以使用

StreamReader.Writeline 

和

StreamRead.ReadLine 

寫入和讀取由換行符分隔的文本塊。
