一個表單，只包括一個dataGridView。

#endregion
private System.Windows.Forms.DataGridView dataGridView1;
private System.Windows.Forms.DataGridViewTextBoxColumn Id;
private System.Windows.Forms.DataGridViewTextBoxColumn Name;
private System.Windows.Forms.DataGridViewTextBoxColumn Price;
}
}
僅從這里就看出來，代碼里有雙重含義的.this.Name
邏輯代碼也出來好了

編譯出錯：CS0029 無法將型別“string”隱式轉換為“System.Windows.Forms.DataGridViewTextBoxColumn” WindowsFormsApp1 C:\Users\qlzcl\source\repos\WindowsFormsApp1\WindowsFormsApp1\Form1.Designer.cs 78 活動
78行就是設計檔案中的this.Name="Form1"，因為前面已經指定了一個this.Name是列屬性。
我想問一下，這是不是一個bug，當然完全可以資料源不要用name屬性就可以了，但是這個問題很奇怪吧

提示是正確的，該換思路去看待問題，之前遇到過，去掉就可以了。uj5u.com熱心網友回復：
這有什么奇怪的，你的name覆寫了原來name的定義，相當于有2個name你定義一個變數2種型別，怎么能不報錯呢
