1. 根据上面的链接，做好各种准备工作

2.HTML tag

2. 添加命名空间

using MODI;using System.IO;

3.上传文件事件

protected void Unnamed_Click(object sender, EventArgs e)        {            string filePath = Server.MapPath("~/Image/" + Path.GetFileName(FileUpload1.PostedFile.FileName));            FileUpload1.SaveAs(filePath);            string extractText = this.ExtractTextFromImage(filePath);            lblText.Text = extractText.Replace(Environment.NewLine, "
");        }

 4.从图片文件中获取Text方法

private string ExtractTextFromImage(string filePath)        {            MODI.Document modiDocument = new MODI.Document();            modiDocument.Create(filePath);               modiDocument.OCR(MiLANGUAGES.miLANG_CHINESE_SIMPLIFIED,true,true);            MODI.Image modiImage = (modiDocument.Images[0] as MODI.Image);            string extractedText = modiImage.Layout.Text;            modiDocument.Close();            return extractedText;        }
