Delete a file from Azure Data Lake store using .Net SDK? - authentication

Question

I want to delete a specific file in the Azure Data Lake Store using .Net SDK
Used the Below code and it returns the error "Operation returned an invalid status code 'BadRequest'"
var clientCredential = new ClientCredential(CLIENTID, CLIENTSECRET);
var creds = ApplicationTokenProvider.LoginSilentAsync(DOMAINNAME,
clientCredential).Result;
_adlsFileSystemClient = new DataLakeStoreFileSystemManagementClient(creds);
var fileDeleteResult = _adlsFileSystemClient.FileSystem.Delete(_adlsAccountName, path);

I used to get this error, which I ended up solving by using the asynchronous methods instead of the synchronous methods.
You might also want to check the file path which you are passing to the "Delete" function; it has to be the whole path, including file name + extension. Something like "/rootFolder/subFolder1/subFolder2/DeleteMe.txt"
Try something like this:
private ServiceClientCredentials Authenticate(string _adlsDomain, string _adlsWebClientId, string _adlsClientSecret)
{
SynchronizationContext.SetSynchronizationContext(new SynchronizationContext());
/*_adlsDomain ==> DirectoryID or TenantID
_adlsWebClientId ==> Application ID
_adlsClientSecret ==> Active Directory APplication key1
*/
ClientCredential clientCredential = new ClientCredential(_adlsWebClientId, _adlsClientSecret);
return ApplicationTokenProvider.LoginSilentAsync(_adlsDomain, clientCredential).Result;
}
private async Task DeleteFile(string path)
{
string _adlsDomain = "xxxx";
string _adlsWebClientId = "xxxx";
string _adlsClientSecret = "xxxx";
string _subscription_id = "xxxx";
string _adlsAccountName = "xxxxxxx";
ServiceClientCredentials _creds = Authenticate(_adlsDomain, _adlsWebClientId, _adlsClientSecret)
// Create client objects and set the subscription ID
DataLakeStoreAccountManagementClient _adlsClient = new DataLakeStoreAccountManagementClient(_creds) { SubscriptionId = _subscription_id };
DataLakeStoreFileSystemManagementClient _adlsFileSystemClient = new DataLakeStoreFileSystemManagementClient(_creds);
await _adlsFileSystemClient.FileSystem.DeleteAsync(_adlsAccountName, path);
}
