i've been try with this function but it's always

Microsoft.SharePoint.Client.ServerException: 'The destination file already exists

public void CopyFile(string SrcUrl, string DestUrl)
    {
        MoveCopyOptions option = new MoveCopyOptions();
        option.KeepBoth = false;
        MoveCopyUtil.CopyFile(this.clientContext,SrcUrl,DestUrl,true,option);

Answer 1

You can create a object of MoveCopyOptions that has boolean property KeepBoth. To handle similar file names you can set MoveCopyOptions. If you want to preserve both file after copying/moving set MoveCopyOptions.KeepBoth to true, else make it false.
