将 ttf 嵌入为嵌入资源:无法引用它 [英] embed ttf as embeded resource: can't reference it

问题描述

我刚刚将一个 ttf 文件添加到项目 (c# 2008 express) 作为文件"和嵌入资源的构建选项.

我在尝试设置这种字体时遇到问题:(我知道下一行是错的...)

this.label1.Font = AlarmWatch.Properties.Resources.Baby_Universe;

<块引用>

错误 1 ​​不能隐式转换类型'字节[]'到'System.Drawing.Font' C:\Users\hongo\Documents\Visual工作室2008\Projects\AlarmWatch\AlarmWatch\Form1.Designer.cs 57 32 AlarmWatch

我知道它是 byte[] 因为我已将选项 build 设置为嵌入式资源，但与正确的这一行进行比较:

this.label1.Font = new System.Drawing.Font("OCR A Extended",24F，System.Drawing.FontStyle.Regular，System.Drawing.GraphicsUnit.Point, ((byte)(0)));

如何设置 this.label1 以使用新字体?

解决方案

System.Drawing.Text 命名空间中有一个 AddMemoryFont 方法，它从一个内存(它需要一个指向内存块的指针，所以你需要做一些不安全的操作来获取指向你的字节数组的指针 - 我找到了一个 示例).详细了解 MSDN 上的方法.

还有一个相关的 StackOverflow 问题展示了如何导入Win API函数直接加载字体(以防上述.NET方法不起作用).

编辑 Visual Basic 中关键部分的翻译可能如下所示(虽然尚未检查):

//这应该是某个类的字段PrivateFontCollection pfc = new PrivateFontCollection();//分配内存并将 byte[] 复制到该位置IntPtr 数据 = Marshal.AllocCoTaskMem(yourByteArray.Length);Marshal.Copy(yourFontArray, 0, data, yourFontArray.Length);//将字体传递给字体集合pfc.AddMemoryFont(data, fontStream.Length)//释放不安全的内存Marshal.FreeCoTaskMem(数据)

一旦你有了这个，你应该能够使用它的常用名称来引用字体.

I've just added a ttf file to the project (c# 2008 express) as "file" and build option to embedded resource.

I'm having problems when trying to set this font like this: (I know the next line is wrong...)

this.label1.Font = AlarmWatch.Properties.Resources.Baby_Universe;

Error 1 Cannot implicitly convert type 'byte[]' to 'System.Drawing.Font' C:\Users\hongo\Documents\Visual Studio 2008\Projects\AlarmWatch\AlarmWatch\Form1.Designer.cs 57 32 AlarmWatch

I know it is byte[] cause I've set the option build as embedded resource, but comparing with this line that is correct:

this.label1.Font = new System.Drawing.Font("OCR A Extended",
                           24F, System.Drawing.FontStyle.Regular,
                           System.Drawing.GraphicsUnit.Point, ((byte)(0)));

How can I set this.label1 to use the new font?

解决方案

There is a AddMemoryFont method in the System.Drawing.Text namespace, which loads a font from a memory (it takes a pointer to the memory block, so you'll need to do some unsafe operation to get pointer to your byte array - I found an example here). More about the method on MSDN.

There is also a related StackOverflow question showing how to import Win API function to load the font directly (in case the above .NET method doesn't work).

EDIT A translation of the key part from Visual Basic might look like this (haven't checked it though):

// This should be probably a field of some class
PrivateFontCollection pfc = new PrivateFontCollection();

// allocate memory and copy byte[] to the location
IntPtr data = Marshal.AllocCoTaskMem(yourByteArray.Length);
Marshal.Copy(yourFontArray, 0, data, yourFontArray.Length);

// pass the font to the font collection
pfc.AddMemoryFont(data, fontStream.Length)

// Free the unsafe memory
Marshal.FreeCoTaskMem(data)

Once you have this, you should be able to refer to the font using its usual name.
