c# API实现简繁体转换的方法(kernel32.dll)

1.using System.Runtime.InteropServices;

2.import kernel32.dll

[DllImport("kernel32.dll", EntryPoint = "LCMapStringA")]
    public static extern int LCMapString(int Locale, int dwMapFlags, byte[] lpSrcStr, int cchSrc, byte[] lpDestStr, int cchDest);
    const int LCMAP_SIMPLIFIED_CHINESE = 0x02000000;
    const int LCMAP_TRADITIONAL_CHINESE = 0x04000000;

3.转简体

//转简体
    protected void btnCHS_Click(object sender, EventArgs e)
    {
        string src =TextBox1.Text.Trim();
        byte[] srcByte = Encoding.Default.GetBytes(src);
        byte[] desByte = new byte[srcByte.Length];
        LCMapString(2052, LCMAP_SIMPLIFIED_CHINESE, srcByte, -1, desByte, srcByte.Length);
        string des = Encoding.Default.GetString(desByte);
       
        TextBox2.Text = des;

    }

4.转繁体

 //繁转简
    protected void btnCHZ_Click(object sender, EventArgs e)
    {
        string src = TextBox1.Text.Trim();
        byte[] srcByte = Encoding.Default.GetBytes(src);
        byte[] desByte = new byte[srcByte.Length];

        LCMapString(2052, LCMAP_TRADITIONAL_CHINESE, srcByte, -1, desByte, srcByte.Length);
        string des = Encoding.Default.GetString(desByte);
        TextBox2.Text = des; 

    }
