Maybe this can help you out:

Using the code:

public string OneDriveApiRoot { get; set; } = "https://api.onedrive.com/v1.0/";
Upload file to OneDrive

//this is main method of upload file to OneDrive 
public async Task<string> UploadFileAsync(string filePath, string oneDrivePath) 
{ 
    //get the upload session,we can use this session to upload file resume from break point 
    string uploadUri = await GetUploadSession(oneDrivePath); 

    //when file upload is not finish, the result is upload progress, 
    //When file upload is finish, the result is the file information. 
    string result = string.Empty; 
    using (FileStream stream = File.OpenRead(filePath)) 
    { 
        long position = 0; 
        long totalLength = stream.Length; 
        int length = 10 * 1024 * 1024; 

        //In one time, we just upload a part of file 
        //When all file part is uploaded, break out in this loop 
        while (true) 
        { 
        //Read a file part 
        byte[] bytes = await ReadFileFragmentAsync(stream, position, length); 

        //check if arrive file end, when yes, break out with this loop 
        if (position >= totalLength) 
        { 
            break; 
        } 

        //Upload the file part 
        result = await UploadFileFragmentAsync(bytes, uploadUri, position, totalLength); 

        position += bytes.Length; 
    } 
} 

return result;

Hi Jagadeesha Ravibabu,
I viewed your description, what graphical API you used? Could you provide some related code to reproduce the situation?
And here are some threads about uploading  the files to the Onedrive you can refer to.
