C# DataGridView 移動/指定 目前選擇的欄位 (DataGridView – Focus a specific cell)

原文問題: 
How to set focus on any specified cell in DataGridView? 
I was expecting a simple way like Focus(rowindex,columnindex) but it is not that easy.

DataGridView1.CurrentCell = DataGridView1.Rows[rowindex].Cells[columnindex];//該欄位不能是隱藏欄位
