好吧,您可以通过连接上面给定的 Paul 示例应用程序动态更新数组来使用动态图像,
string[] files = {
"readme.htm", "desert.jpg", "sample.jpg"
};
在写隔离之前,您可以删除现有的
private void SaveFilesToIsoStore()
{
//These files must match what is included in the application package,
//or BinaryStream.Dispose below will throw an exception.
string[] files = {
"readme.htm", "desert.jpg", "sample.jpg"
};
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
if(isoStore.FileExists(files[0]))
{
isoStore.DeleteFile(files[0]);
}
foreach (string f in files)
{
StreamResourceInfo sr = Application.GetResourceStream(new Uri(f, UriKind.Relative));
using (BinaryReader br = new BinaryReader(sr.Stream))
{
byte[] data = br.ReadBytes((int)sr.Stream.Length);
SaveToIsoStore(f, data);
}
}
}
private void SaveToIsoStore(string fileName, byte[] data)
{
string strBaseDir = string.Empty;
string delimStr = "/";
char[] delimiter = delimStr.ToCharArray();
string[] dirsPath = fileName.Split(delimiter);
//Get the IsoStore.
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
//Re-create the directory structure.
for (int i = 0; i < dirsPath.Length - 1; i++)
{
strBaseDir = System.IO.Path.Combine(strBaseDir, dirsPath[i]);
isoStore.CreateDirectory(strBaseDir);
}
//Remove the existing file.
if (isoStore.FileExists(fileName))
{
isoStore.DeleteFile(fileName);
}
//Write the file.
using (BinaryWriter bw = new BinaryWriter(isoStore.CreateFile(fileName)))
{
bw.Write(data);
bw.Close();
}
}
