Hello,

Below is my code for creating a new JSON file in C#.. It gives an error "Object reference not set to an instance of an object.".. What is going wrong?
________________________________________________________________________________________________
Content.data.Add(de);            

string outputJSON = JsonConvert.SerializeObject(Content); //outputJSON is working fine
csfilStorageFile = await csfldrStorFolder.CreateFileAsync(clsDeclarations.gsDataFileName, Windows.Storage.CreationCollisionOption.ReplaceExisting); //The error is caught here

await FileIO.WriteTextAsync(csfilStorageFile , outputJSON);
________________________________________________________________________________________________

Regards.

Maybe csfldrStorFolder or clsDeclarations is null.

No, csfldrStorFolder has been created previous to this, the folder is being created. And clsDeclarations holds names for various strings, it exists too. :(
