public System.Drawing.Color Color { get; set; }

member this.Color : System.Drawing.Color with get, set

Public Property Color As Color

屬性值

Color

Color 值，表示插入標記的色彩。 預設值為 ForeColor 屬性的值。

範例

下列程式碼範例示範如何使用 ListView 插入標記功能，並使用標準拖曳事件來實作拖放專案重新排序。 插入標記的位置會在事件的處理常式 Control.DragOver 中更新。 在此處理程式中，滑鼠指標的位置會與最接近專案的中間點進行比較，而結果會用來判斷插入標記是否出現在專案的左邊或右邊。

如需完整的範例，請參閱 ListViewInsertionMark 概觀參考主題。
