如何在C＃中为带有.NET 2.0的Windows CE 5.0应用程序使用AddFontResource [英] How to use AddFontResource in c# for Windows CE 5.0 application with .NET 2.0

问题描述

我正在尝试使用Visual Stdio 2008 pro和.NET 2.0的c＃在汽车中为Windows CE 5.0设备开发智能设备程序。我想使用AddFontResourceEx添加字体，但无法使其正常工作。这是代码：

I'm trying to develop a Smart Device program for Windows CE 5.0 device in my car with Visual Stdio 2008 pro and c# with .NET 2.0. I want to add a font using AddFontResourceEx, but I can't get it to work. Here is the code:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }
    private const uint FR_PRIVATE=0x10;
    [DllImport("GDI32.dll",EntryPoint="AddFontResourceEx")]
    static extern int AddFontResourceEx(string lpszFilename, uint fl, IntPtr pdv);

    private void button1_Click(object sender, EventArgs e)
    {
        AddFontResourceEx(".\\ELEPHNT.TTF", FR_PRIVATE, IntPtr.Zero);
       label1.ForeColor = Color.FromArgb(155, 25, 34);
       label1.Font = new Font("ELEPHNT.TTF", 18, FontStyle.Regular);
       label1.Text = "Hello world!";
    }
}

它可以成功构建，并且我可以运行该程序，但是字体不会改变。我将字体文件添加到程序所在的目录中。

It builds succesfully and I can run the program, but the font won't change. I added the font file to the same directory where the program is. Could you please tell me what is wrong?

推荐答案

您不能在C＃代码中使用C ++声明，请使用pinvoke和兼容的数据类型：
http：// www.pinvoke.net/search.aspx?search=addfontresource&namespace= [全部]
在Windows CE中没有相对路径，因此您必须使用字体文件的完整路径。 ，从。

You can't use a C++ declaration inside C# code, you need to use pinvoke and compatible data types: http://www.pinvoke.net/search.aspx?search=addfontresource&namespace=[All] In Windows CE there is no relative path, so you'll have to use the full path of your font file, starting from .
