使用 Dropbox .NET 庫獲取檔案的共享連結

此示例使用 Dropbox .NET 庫獲取檔案的共享連結，方法是建立新檔案或檢索現有檔案：

SharedLinkMetadata sharedLinkMetadata;
try {
    sharedLinkMetadata = await this.client.Sharing.CreateSharedLinkWithSettingsAsync (path);
} catch (ApiException<CreateSharedLinkWithSettingsError> err) {
    if (err.ErrorResponse.IsSharedLinkAlreadyExists) {
        var sharedLinksMetadata = await this.client.Sharing.ListSharedLinksAsync (path, null, true);
        sharedLinkMetadata = sharedLinksMetadata.Links.First();
    } else {
        throw err;
    }
}
Console.WriteLine (sharedLinkMetadata.Url);
