选择图片及上传按钮代码如下：

private void button1_Click (object sender, EventArgs e) {
    try {
        richTextBox1.Text = "";
        Openimgfile (); //调用文件打开对话框
        this.button1.Text = "上传并提取中...";
        pictureBox1.LoadAsync (textBox1.Text);
        GeneralBasicDemo ();
        调用百度ai接口
    } catch (Exception ex) {
        MessageBox.Show ("报错,原因：" + ex.Message, "错误", MessageBoxButtons.OK, MessageBoxIcon.Warning);

    }
}

打开文件对话框过程代码：

//打开文件模块
public void Openimgfile () {
    try {
        OpenFileDialog dialog = new OpenFileDialog ();
        dialog.Filter = "图片(*.png;*.jpg;*.bmp;*.jpeg)|*.png;*.jpg;*.bmp;*.jpeg";

        if (dialog.ShowDialog () == DialogResult.OK) {
            this.textBox1.Text = dialog.FileName;
        }
    } catch (Exception ex) {
        MessageBox.Show ("报错,原因：" + ex.Message, "错误", MessageBoxButtons.OK, MessageBoxIcon.Warning);
    }

}

调用百度api接口 过程代码：

public void GeneralBasicDemo () {

    try {
        string Json;
        var APP_ID = "123456";
        var API_KEY = "123456";
        var SECRET_KEY = "123456";

        var client = new Baidu.Aip.Ocr.Ocr (API_KEY, SECRET_KEY);
        client.Timeout = 60000;

        var image = File.ReadAllBytes (textBox1.Text);
        var result = client.GeneralBasic (image);
        Console.WriteLine (result);
        // 如果有可选参数
        var options = new Dictionary<string, object> { { "language_type", "CHN_ENG" },
                { "detect_direction", "true" },
                { "detect_language", "true" },
                { "probability", "true" }
            };

        result = client.GeneralBasic (image, options);
        //Console.WriteLine(result);

        //richTextBox1.Text = result.ToString();
        Json = result.ToString ();
        Json_get (Json);
        this.button1.Text = "选择图片并提取文字";

    } catch (Exception ex) {
        MessageBox.Show ("报错,原因：" + ex.Message, "错误", MessageBoxButtons.OK, MessageBoxIcon.Warning);
        this.button1.Text = "选择图片并提取文字";
    }
}

百度返回的内容是json格式,需要从json中提取words关键字对应的值, 若需要,请留言,我单独发邮箱
