在IsolatedStorage中重命名文件

您可以打开现有文件,将其复制到新文件并删除旧文件。这将是缓慢的行动相比,但这可能是唯一的办法。

var oldName = "file.old"; var newName = "file.new";

using (var store = IsolatedStorageFile.GetUserStoreForApplication())
using (var readStream = new IsolatedStorageFileStream(oldName, FileMode.Open, store))
using (var writeStream = new IsolatedStorageFileStream(newName, FileMode.Create, store))
using (var reader = new StreamReader(readStream))
using (var writer = new StreamWriter(writeStream))
{
  writer.Write(reader.ReadToEnd());
}

完美地执行这段代码

string oldName="oldName";
string newName="newName";
var file = await ApplicationData.Current.LocalFolder.GetFileAsync(oldName);
await file.RenameAsync(newName);
