嗨Arun Singh Rawat，

尝试第三个像
syncfusion 这样的派对图书馆可以完成一些任务但不是全部。

在通用Windows平台中，没有这样的API来读取/写入Microsoft文档。 

但是，您可以在其与指定文件关联的默认应用程序中打开任何文档文件。&nbsp ;使用下面的代码。

 private async void Button_Click（object sender，RoutedEventArgs e）
 {
 StorageFile file = null; 

 //要通过Picker打开文件，取消注释
 // FileOpenPicker openPicker = new FileOpenPicker（）; 
 //openPicker.FileTypeFilter.Add(".docx"）; 
 // file = await openPicker.PickSingleFileAsync（）

 //从App的LocalFolder打开文件
 var file = await ApplicationData.Current.LocalFolder.GetFileAsync（" Test。 DOCX&QUOT）; 

 if（file！= null）
 {
 //启动检索到的文件
等待Windows.System.Launcher.LaunchFileAsync（file）; 
} 
} 

如果它解决了你的问题，请标记为答案。

谢谢。

Hi Arun Singh Rawat,

Try a third party library like syncfusion to do some of the tasks but not all.

In Universal Windows Platform there is no such API to read/write Microsoft documents. 

However you can open any document file in it's default app associated with the specified file. using the below code.

private async void Button_Click(object sender, RoutedEventArgs e)
{
    StorageFile file = null;

    //To Open file by Picker, Uncomment
    //FileOpenPicker openPicker = new FileOpenPicker();
    //openPicker.FileTypeFilter.Add(".docx");
    //file = await openPicker.PickSingleFileAsync()

    //To Open file from App's LocalFolder
    var file = await ApplicationData.Current.LocalFolder.GetFileAsync("Test.docx");

    if (file != null)
    {
        // Launch the retrieved file
        await Windows.System.Launcher.LaunchFileAsync(file);
    }
}

Mark as Answer if it solved your issue.

Thanks.
