如何：列舉已安裝的字型

InstalledFontCollection 類別繼承自抽象基底類別 FontCollection。 您可以使用 InstalledFontCollection 物件來列舉電腦上安裝的字型。 InstalledFontCollection 物件的 Families 屬性是 FontFamily 物件的陣列。

範例

下列範例會列出電腦上所安裝所有字型系列的名稱。 程式碼會擷取 Families 屬性所傳回陣列中每個 FontFamily 物件的 Name 屬性。 擷取姓氏時，會串連成以逗號分隔的清單。 然後，Graphics 類別的 DrawString 方法會在矩形中繪製逗號分隔清單。

如果您執行範例程式碼，輸出會類似於下圖所示：

FontFamily fontFamily = new FontFamily("Arial");
Font font = new Font(
   fontFamily,
   8,
   FontStyle.Regular,
   GraphicsUnit.Point);
RectangleF rectF = new RectangleF(10, 10, 500, 500);
SolidBrush solidBrush = new SolidBrush(Color.Black);

string familyName;
string familyList = "";
FontFamily[] fontFamilies;

InstalledFontCollection installedFontCollection = new InstalledFontCollection();

// Get the array of FontFamily objects.
fontFamilies = installedFontCollection.Families;

// The loop below creates a large string that is a comma-separated
// list of all font family names.

int count = fontFamilies.Length;
for (int j = 0; j < count; ++j)
{
    familyName = fontFamilies[j].Name;
    familyList = familyList + familyName;
    familyList = familyList + ",  ";
}

// Draw the large string (list of all families) in a rectangle.
e.Graphics.DrawString(familyList, font, solidBrush, rectF);

Dim fontFamily As New FontFamily("Arial")
Dim font As New Font( _
   fontFamily, _
   8, _
   FontStyle.Regular, _
   GraphicsUnit.Point)
Dim rectF As New RectangleF(10, 10, 500, 500)
Dim solidBrush As New SolidBrush(Color.Black)

Dim familyName As String
Dim familyList As String = ""
Dim fontFamilies() As FontFamily

Dim installedFontCollection As New InstalledFontCollection()

' Get the array of FontFamily objects.
fontFamilies = installedFontCollection.Families

' The loop below creates a large string that is a comma-separated
' list of all font family names.
Dim count As Integer = fontFamilies.Length
Dim j As Integer

While j < count
    familyName = fontFamilies(j).Name
    familyList = familyList & familyName
    familyList = familyList & ",  "
    j += 1
End While

' Draw the large string (list of all families) in a rectangle.
e.Graphics.DrawString(familyList, font, solidBrush, rectF)

編譯程式碼

上述範例的設計目的是要與 Windows Forms 搭配使用，而且需要 PaintEventArgse，這是 PaintEventHandler 的參數。 此外，您應該匯入 System.Drawing.Text 命名空間。
