推荐答案

您好NNos2012，



您可以获取div标签并可以替换代码中的标签，以便在前端看不到该div。我有一些代码你可以尝试一下......

Hi NNos2012,

You can get the div tag and can replace the tag in code so that that div will not be visible on front end. I have some code you can try them out...

string replaceString = string.Join(";",
                           File.ReadAllLines("<div id="id1">")
                           ).Replace("@", "<div id="id1" style="display: none;">");

   File.WriteAllText("<div id="id1">", replaceString);
   Console.WriteLine("Done");
   Console.ReadLine();</div></div></div>

或者尝试以下代码：

Or try the following code:

// Open a file for reading
StreamReader streamReader
streamReader = File.OpenText(fileName)
// Now, read the entire file into a strin
string contents = streamReader.ReadToEnd();
streamReader.Close()

// Write the modification into the same fil
StreamWriter streamWriter=File.CreateText(fileName);

streamWriter.Write(contents.Replace("String1", "String2"));
streamWriter.Close();

在我的表单中我已经拍摄文本框和按钮



点击按钮事件

Here I am developed Win Form application To delete Div Section from Text file

on click button event

private void button1_Click(object sender, EventArgs e)
        {
            string search = "<div id=\"" + textBox1.Text + "\">";
            List<string> lines = new List<string>(File.ReadAllLines("Your File Path"));
            foreach (string line in lines)
            {
                line.TrimStart(); line.TrimEnd();
                if (line.Contains(search))
                {
                    SLineNumber = i;
                }
                if (SLineNumber > 0)
                {
                    count++;
                    if (line.Contains("<div id=") && !line.Contains(search) || line.Contains("<div>"))
                    {
                        innerDiv++;
                    }
                }
                if (line.Contains("</div>") && innerDiv == 0 & SLineNumber != 0)
                {
                    ELineNumber = i;
                    break;
                }
                else if (line.Contains("</div>") && SLineNumber != 0)
                {
                    innerDiv--;
                }
                i++;
            }
            lblSLine.Text = SLineNumber.ToString();
            lblELine.Text = ELineNumber.ToString();
            if (SLineNumber != 0 && ELineNumber != 0)
            {
                 lines.RemoveRange(SLineNumber,ELineNumber-SLineNumber);
                 File.WriteAllLines("Your file Path", lines.ToArray());
                 MessageBox.Show(" Remove the Section of Div " + textBox1.Text);
            }
            else
            {
                MessageBox.Show("Div  id=" + textBox1.Text + "  does not exist");
            }
        }

此代码删除特定ID的Div部分< br $> b $ b
