(C# UWP/WinRT) OneDrive -- List Large Directory

Demonstrates how to get the entire collection of DriveItem children when the collection is large and multiple pages need to be requested. To test this example, I created a DriveItem with 450 children.

Note: This example requires Chilkat v9.5.0.68 or greater.

Chilkat Universal Windows Platform (UWP) / WinRT Downloads

Chilkat for the Universal Windows Platform (UWP)

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Http http = new Chilkat.Http();

// Use your previously obtained access token here:
// See the following examples for getting an access token:
//    Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint).
//    Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint).
//    Refresh Access Token (Azure AD v2.0 Endpoint).
//    Refresh Access Token (Azure AD Endpoint).

// (Make sure your token was obtained with the FilesRead or Files.ReadWrite scope.)
http.AuthToken = "MICROSOFT_GRAPH_ACCESS_TOKEN";

// This example will get the DriveItems in /lots-of-files, which has 450 children..
http.SetUrlVar("item_path","/lots-of-files");

string resp;
int i;
int numItems;

Chilkat.JsonObject json = new Chilkat.JsonObject();
json.EmitCompact = false;

// This loop will download DriveItems in sets of 50 until no more exist.
bool bGetMore = true;
// (Add the $top query parameter to define the page size, i.e. the max number of results to return).
string nextLink = "https://graph.microsoft.com/v1.0/me/drive/root:{$item_path}:/children?$top=50";

while ((bGetMore == true)) {

    // Get the next chunk of DriveItems
    resp = await http.QuickGetStrAsync(nextLink);
    if (http.LastMethodSuccess != true) {
        Debug.WriteLine(http.LastErrorText);
        return;
    }

    // The response should be JSON.
    json.Load(resp);

    // A successful response should return a status code of 200.
    if (http.LastStatus != 200) {
        Debug.WriteLine(json.Emit());
        Debug.WriteLine("Response status = " + Convert.ToString(http.LastStatus));
        return;
    }

    // Iterate over the DriveItems in the JSON response:
    i = 0;
    numItems = json.SizeOfArray("value");
    while (i < numItems) {
        json.I = i;
        Debug.WriteLine("name: " + json.StringOf("value[i].name"));
        i = i + 1;
    }

    // If a nextLink was included in the JSON, use it to get the next set of 50 DriveItems.
    // Otherwise, exit the loop.
    if (json.HasMember("\"@odata.nextLink\"") == true) {
        nextLink = json.StringOf("\"@odata.nextLink\"");
        Debug.WriteLine("nextLink: " + nextLink);
    }
    else {
        bGetMore = false;
    }

}
