如何:在已繪製的文字中設定定位停駐點

您可以呼叫 SetTabStops 物件的 方法,然後將該 StringFormat 物件傳遞至 DrawString 類別的 方法 StringFormat ,以設定文字的 Graphics 定位停駐點。

注意

System.Windows.Forms.TextRenderer不支援將定位停駐點新增至繪製文字,不過您可以使用 旗標展開現有的定位停駐點 TextFormatFlags.ExpandTabs

範例

下列範例會將定位停駐點設定為 150、250 和 350。 然後,程式碼會顯示名稱與測試分數的索引標籤式清單。

下圖顯示索引標籤式文字:

下列程式碼會將兩個引數傳遞至 SetTabStops 方法。 第二個引數是包含定位點位移的陣列。 傳遞至 SetTabStops 的第一個引數為 0,表示陣列中的第一個位移是從周框的左邊緣位置 0 開始測量。

string text = "Name\tTest 1\tTest 2\tTest 3\n";
text = text + "Joe\t95\t88\t91\n";
text = text + "Mary\t98\t84\t90\n";
text = text + "Sam\t42\t76\t98\n";
text = text + "Jane\t65\t73\t92\n";
