Question

我试图通过从文本文件中读取每一行的名称来填充List<Image>。文本文件如下所示：

image0
image1
image2
image
...

以下代码使我的程序完全崩溃并使Visual Studio冻结。

int counter = 0;
string line = string.Empty;
StreamReader file = new StreamReader("ItemFile.txt");

while ((line = file.ReadLine()) != null)
{
     imageCollection.Add(new Image());
     imageCollection[counter].Source = new BitmapImage(new Uri("Images/" + line + ".png", UriKind.Relative));
}

您不能在WP7上使用标准读/写机制。您必须使用IsolatedStorage类来执行此操作：

IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream fileStream = myIsolatedStorage.OpenFile("ItemFile.txt", FileMode.Open, FileAccess.Read);
using (StreamReader reader = new StreamReader(fileStream))
{    //Visualize the text data in a TextBlock text
    while ((line = reader .ReadLine()) != null)
    {
         imageCollection.Add(new Image());
         imageCollection[counter].Source = new BitmapImage(new Uri("Images/" + line + ".png", UriKind.Relative));
    }
}
