1. 根据上面的链接，做好各种准备工作

2.HTML tag

 <div>

      <asp:FileUpload ID="FileUpload1" runat="server" />

      <asp:Button Text="Upload" runat="server" OnClick="Unnamed_Click"/>

<hr />

<asp:Label ID="lblText" runat="server" />

</div>

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, "<br />");

        }

 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;

        }
