來自datagridview的C#按鈕名稱

我想更改按鈕的背面顏色。我知道這個：button1.BackColor = System.Drawing.Color.Yellow;

但我不知道如何從 DataGridView 中獲取按鈕的名稱。我試試這個，但它不作業

string butttonn = "table" c.ToString(); 
butttonn.BackColor = System.Drawing.Color.Yellow;

我想如果按鈕名稱現有訪問資料庫 button.BackColor 更改為綠色，如果按鈕名稱不存在 button.BackColor 更改為紅色。

我不懂英語。我希望我能夠表達自己。

謝謝你們，我解決了這個問題：
