推荐答案

取决于定义段落的方式-如果段落以期望的方式以ENTER结尾，则很简单:

Depends on how you define a Paragraph - if a paragraph ends with an ENTER as you would expect, then it is simple:

int paragraphs = myTextBox.Lines.Length;

可以尝试一下，

Can Try this,

if (Textbox1.Text != "")
{
  int paraCount = Textbox1.Text.Split('\r').Length;
}

try
       {
//made by Muhammad Usman-Bahria University-kai
       string path = args[0];
       FileStream fh = new FileStream(path, FileMode.Open, FileAccess.Read);
       int i;
       string s = "";
       while ((i = fh.ReadByte()) != -1)
       {

           s = s + (char)i;
       }

       int count = 0;
       for (int j = 0; j < s.Length - 1; j++)
       {
           if (s.Substring(j, 1) == "\n")
           {

               count++;
           }
       }

           Console.WriteLine("The total searches were :" + count);

           fh.Close();

       }
           catch(Exception ex)
       {
               Console.WriteLine(ex.Message);
           }
       }
