Merge(ToolStrip, String)
結合相同型別的兩個 ToolStrip 物件。
public:
static bool Merge(System::Windows::Forms::ToolStrip ^ sourceToolStrip, System::String ^ targetName);public static bool Merge (System.Windows.Forms.ToolStrip sourceToolStrip, string targetName);static member Merge : System.Windows.Forms.ToolStrip * string -> boolPublic Shared Function Merge (sourceToolStrip As ToolStrip, targetName As String) As Boolean參數
傳回
如果合併成功，則為 true，否則為 false。
例外狀況
sourceToolStrip 或 targetName 為 null。
sourceToolStrip 或 targetName即為相同的 ToolStrip。
備註
ToolStripManager.Merge使用 方法來結合 ToolStrip 相同類型的物件，例如 ToolStrip 物件與其他 ToolStrip 物件、 MenuStrip 物件與其他 MenuStrip 物件等等。
ToolStripManager.Merge使用 方法來結合 ToolStrip 不同類型的物件。
屬性 ToolStrip.AllowMerge 必須同時設定 true 為 ToolStrip 物件，而且來源和目標型別必須相同，否則這個方法會傳 false 回 。
注意
如果 MDI 子表單上有兩 MenuStrip 個控制項，則父表單的 設定 IsMdiContainer true 為 只會合並其中一個 MenuStrip 控制項的內容。 用來 Merge 合併 MDI 父表單上其他子 MenuStrip 控制項的內容。
