(C#) OneDrive -- Download Text File to Memory

Downloads a text file (such as XML, JSON, plain-text, HTML, etc.) into a StringBuilder object.

Note: This example requires Chilkat v9.5.0.97 or greater.

Chilkat .NET Downloads Chilkat .NET Framework Chilkat for .NET Core

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

// This example uses the OAuth client credentials flow.
// See How to Create an Azure App Registration for OAuth 2.0 Client Credentials

// Use your client ID, client secret, and tenant ID in the following lines
Chilkat.JsonObject json = new Chilkat.JsonObject();
json.UpdateString("client_id","2871da2c-8176-4b7f-869b-2311aa82e743");
json.UpdateString("client_secret","2hu9Q~r5QuryUcEkNbg1btLtnfU1VUXzhSCG6brH");
json.UpdateString("scope","https://graph.microsoft.com/.default");
json.UpdateString("token_endpoint","https://login.microsoftonline.com/114d7ed6-71bf-4dbe-a866-748364121bf2/oauth2/v2.0/token");

Chilkat.Http http = new Chilkat.Http();
http.AuthToken = json.Emit();

// Sends the following GET request:
// GET https://graph.microsoft.com/v1.0/users/{$user_id}/drive/root:/{item-path}:/content

// Make sure to automatically follow redirects
http.FollowRedirects = true;

// This example will download /Misc/hamlet.xml
http.SetUrlVar("item_path","Misc/hamlet.xml");
http.SetUrlVar("user_id","4fe732c3-322e-4a6b-b729-2fd1eb5c6104");

Chilkat.StringBuilder sbXml = new Chilkat.StringBuilder();
string expectedCharset = "utf-8";
string url = "https://graph.microsoft.com/v1.0/users/{$user_id}/drive/root:/{$item_path}:/content";
bool success = http.DownloadSb(url,expectedCharset,sbXml);
if (http.LastMethodSuccess != true) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

// If the response status code was not 200, then it failed.
if (http.LastStatus != 200) {
    Debug.WriteLine("Response Status Code = " + Convert.ToString(http.LastStatus));
    Debug.WriteLine("Failed.");
    return;
}

// If we got here, then the file was successfully downloaded.
Debug.WriteLine("Download from OneDrive successful.");
Debug.WriteLine("The file is contained in sbXml.");
