Winform 窗體設計器 沒法識別重複成員變量聲明的問題

打開窗體設計視圖出現以下錯誤：

查看後臺代碼：

   ColumnHeader colHead;
            colHead = new ColumnHeader();
            colHead.Text = "Ch";
            colHead.Width = 30;
            this.ChList.Columns.Add(colHead);

            colHead = new ColumnHeader();
            colHead.Text = "ChType";
            colHead.Width = 99;
            this.ChList.Columns.Add(colHead);

            colHead = new ColumnHeader();
            colHead.Text = "Status";
            colHead.Width = 78;
            this.ChList.Columns.Add(colHead);


            colHead = new ColumnHeader();
            colHead.Text = "CallerId";
            colHead.Width = 80;
            this.ChList.Columns.Add(colHead);

            colHead = new ColumnHeader();
            colHead.Text = "CalleeId";
            colHead.Width = 80;
            this.ChList.Columns.Add(colHead);
            //
            colHead = new ColumnHeader();
            colHead.Text = "DTMFBuffer";
            colHead.Width = 80;
            this.ChList.Columns.Add(colHead);

 

發現設計器不能識別相同變量的聲明不一樣的實例。

 將每一個ColumnHeader 都聲明一次 解決問題
