正如你在App memory limits for Windows Phone 8中看到的，你可以找到一些关于Windows应用程序内存限制的信息。

正如你所看到的一些workaround about memory statistics，你可以在C#中使用下面的一些API

private void buttonGetMemoryMetrics_Click(object sender, RoutedEventArgs e)
        {
            
            long totalBytes = DeviceStatus.DeviceTotalMemory;
            long usageLimit = DeviceStatus.ApplicationMemoryUsageLimit;
            long currentUsage = DeviceStatus.ApplicationCurrentMemoryUsage;
            ulong commitLimit = MemoryManager.ProcessCommittedLimit;
            ulong currentCommit = MemoryManager.ProcessCommittedBytes;
 
            long workingsetLimit = 0;
            object temp;
            if(DeviceExtendedProperties.TryGetValue("ApplicationWorkingSetLimit", out temp))
                workingsetLimit = (long)temp;
 
 
            textBlockApplicationCurrentMemoryUsage.Text = currentUsage.ToString();
            textBlockApplicationMemoryUsageLimit.Text = usageLimit.ToString();
            textBlockApplicationWorkingSetLimit.Text = workingsetLimit.ToString();
            textBlockBytesCommitLimit.Text = commitLimit.ToString();
            textBlockBytesCommitted.Text = currentCommit.ToString();
            textBlockDeviceTotalMemory.Text = totalBytes.ToString();
            
        }

对于C++的用法，你可以看到MemoryManager.AppMemoryUsageLimit。你可以在MemoryManager部分找到一些关于API的有用信息。
