试试这个

 Private Sub GetFileList（ParentFolder As  String ）

授权（）' 照顾授权......你可以用JS来询问用户和获取Auth令牌

' MSO  -   20130423   - 使用指定的foldername 
' 创建搜索请求
 Dim oListReq As Google.Apis.Drive.v2.FilesResource.ListRequest 
 Dim oFileList As FileList 
' mimeType = '  application / vnd.google-apps.folder' 

 oListReq = oDriveService .Files.List（）
' 搜索特定文件名
 oListReq.Q = mimeType =' application / vnd.google-apps.folder '  and title ='   + ParentFolder + ' 和trashed = false
 oListReq.Fields =items / id' MSO  -   20130621   - 仅限ID  下一个查询
 oListReq.MaxResults =  10  ' 最多10个文件（也可能只有1个）

'获取结果
 oFileList = oListReq .Fetch（）

' 预计只有1个结果
如果oFileList.Items.Count = 1那么
 Dim oFile As File = oFileList.Items（0）
 FolderId = oFile.Id'获取FolderId 
结束如果

 oListReq = oDriveService.Files.List（）
' 在
 oListReq.Q ='   + FolderId + ' 和trashed = false
' oListReq.Fields =   items（id，alternateLink） '  MSO  -  20130621  - 如果只需要某些字段，请优化查询

'获取结果
 oFileList = oListReq.Fetch（）

'n>  TODO：oFileList现在有文件夹中的文件列表，但可能有更多页面

 End Sub  

I want to load my slider of image which image comes from google drive or one drive. i used below code for google drive but it returns all the files and i want to get from specific folder.

GoogleConnect.ClientId = "xxxxxx";
GoogleConnect.ClientSecret = "xxxxxx";
GoogleConnect.RedirectUri = Request.Url.AbsoluteUri.Split('?')[0];
GoogleConnect.API = EnumAPI.Drive;
if (!string.IsNullOrEmpty(Request.QueryString["code"]))
{
    string code = Request.QueryString["code"];
    string json = GoogleConnect.Fetch("me", code);
    GoogleDriveFiles files = new JavaScriptSerializer().Deserialize<GoogleDriveFiles>(json); // This will returns the files      
}
else if (Request.QueryString["error"] == "access_denied")
{
    ClientScript.RegisterClientScriptBlock(this.GetType(), "alert", "alert('Access denied.')", true);
}

try this

Private Sub GetFileList(ParentFolder As String)

    Authorize() 'Take care of authorization... you could use JS to ask the user and get the Auth Token

    'MSO - 20130423 - Search the Google Drive File with the specified foldername
    'Create the search request
    Dim oListReq As Google.Apis.Drive.v2.FilesResource.ListRequest
    Dim oFileList As FileList
    'mimeType = 'application/vnd.google-apps.folder'

    oListReq = oDriveService.Files.List()
    'Search for a specific file name
    oListReq.Q = "mimeType = 'application/vnd.google-apps.folder' and title = '" + ParentFolder + "' and trashed=false"
    oListReq.Fields = "items/id" 'MSO - 20130621 - only ID needed for next query
    oListReq.MaxResults = 10 'Max 10 files (too may I Expect only 1)

    'Get the results
    oFileList = oListReq.Fetch()

    'Only 1 result is expected
    If oFileList.Items.Count = 1 Then
        Dim oFile As File = oFileList.Items(0)
        FolderId = oFile.Id 'Get FolderId
    End If

    oListReq = oDriveService.Files.List()
    'Search for a specific file name in the folder
    oListReq.Q = "'" + FolderId + "' in parents and trashed=false "
    'oListReq.Fields = "items(id,alternateLink)" 'MSO - 20130621 - Optimize your query if you need only certain fields

    'Get the results
    oFileList = oListReq.Fetch()

    'TODO: oFileList now have the list of the files in the folder, but there could me more "pages"
