试试这个

try this

 private void Form1_Load(object sender, EventArgs e)
        {
byte[] imageArray = System.IO.File.ReadAllBytes(@"F:\WebApplication1\WindowsFormsApplication1\eMeditime_logo_edited.png");
           string base64ImageRepresentation = Convert.ToBase64String(imageArray);
           using (StreamWriter writer = new StreamWriter(@"F:\ccon\abc.txt", true))
           {
               writer.Write(base64ImageRepresentation);
               writer.Flush();
               writer.Close();
           }
}

它会将图像转换为base64但不会从图像中提取数据以执行您需要的OCR
