本文实例讲述了C#实现统计字数功能的方法。分享给大家供大家参考。具体如下：

1.程序效果示例如下：

2.程序控件用法：

3.程序代码：

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;using System.IO;namespace Program18{ public partial class FormMain : Form { public FormMain() { InitializeComponent(); } private void btnRead_Click(object sender, EventArgs e) { try { txtWords.Text = File.ReadAllText(txtFileAddr.Text); } catch (Exception ex) { MessageBox.Show(ex.Message); } } private void txtWords_TextChanged(object sender, EventArgs e) { int iAllChr = 0; //字符总数：不计字符'\n'和'\r' int iChineseChr = 0; //中文字符计数 int iChinesePnct = 0;//中文标点计数 int iEnglishChr = 0; //英文字符计数 int iEnglishPnct = 0;//中文标点计数 int iNumber = 0; //数字字符：0-9 foreach (char ch in txtWords.Text) { if (ch != '\n' && ch != '\r') iAllChr++; if ("～！＠＃￥％…＆（）—＋－＝".IndexOf(ch) != -1 || "｛｝【】：“”；‘'《》，。、？｜＼".IndexOf(ch) != -1) iChinesePnct++; if (ch >= 0x4e00 && ch <= 0x9fbb) iChineseChr++; if ("`~!@#$%^&*()_+-={}[]:\";'<>,.?/\\|".IndexOf(ch) != -1) iEnglishPnct++; if ((ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z')) iEnglishChr++; if (ch >= '0' && ch <= '9') iNumber++; } string sStats = string.Format(string.Concat( "字符总数：{0}\r\n", "中文字符数：{1}\r\n", "中文标点数：{2}\r\n", "英文字符数：{3}\r\n", "英文标点数：{4}\r\n", "数字字符数：{5}\r\n"), iAllChr.ToString(), iChineseChr.ToString(), iEnglishChr.ToString(), iEnglishChr.ToString(), iEnglishPnct.ToString(), iNumber.ToString()); txtStats.Text = sStats; } }}

希望本文所述对大家的C#程序设计有所帮助。
