namespace 图片识别
{
    public partial class Form1 : Form
    {

        public Form1()
        {

            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            DialogResult dr = openFileDialog1.ShowDialog(this);
            textBox1.Text = openFileDialog1.FileName;
        }

        private void button2_Click(object sender, EventArgs e)
        {
            richTextBox1.Text = Marshal.PtrToStringAnsi(OCR(textBox1.Text, -1));
            //MessageBox.Show(Marshal.PtrToStringAnsi(OCRpart(img_path, -1, startX, startY, width, height)));
        }

    }
}

需要引入一个DLL    AspriseOCR.dll   这个可以从网上下载
