C#在dataGridView中遍历

int row = dataGridView1.Rows.Count;//得到总行数 
 
            int cell=dataGridView1.Rows[1].Cells.Count;//得到总列数 
 
            for (int i = 0; i <  row; i++)//得到总行数并在之内循环 
 
            {   
                for (int j = 0; j <  cell; j++)//得到总列数并在之内循环 
 
                {   
                    if (txtFind.Text == dataGridView1.Rows.Cells[j].Value.ToString())   

                    {   //对比TexBox中的值是否与dataGridView中的值相同（上面这句） 
 
                        this.dataGridView1.CurrentCell =
this.dataGridView1[j, i];//定位到相同的单元格 
 
                        return;//返回 
 
                    }   
                     
                }
