C#统计字符串的方法
本文实例为大家分享了C#字数统计(字母、数字、汉字、符号)的具体代码,供大家参考,具体内容如下
namespace 测试1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
this.richTextBox1.Text = "g你\rs\rs你好吗d dsDDDDDDDDddssssss、‘\\奇巧';‘l;''''sssssssssssssssssssssssssssssssssssssssssssssssssssssssssasdddddddddddddddddddd\tddddddddddddddddddddddddddddddddddddddddddddddddda";
}
bool skipSpace = true;
//窗口加载
private void Form1_Load(object sender, EventArgs e)
{
richTextBox1.Focus();
int cnt1=0, cnt2=0, cnt3=0, cnt4=0;
if (this.richTextBox1.Text != null)
{
string sLine;
string s = richTextBox1.Text;
if (skipSpace)
{
{
sLine = s.Replace(" ?", "").Replace(" ", "").Replace("\t", "").Replace("\n", "").Replace("\r", "");
cnt2 += getByteLength(sLine);
cnt1 += getWordLength(sLine);
cnt3 += getdigitalLength(sLine);
cnt4 += getcharLength(sLine);
textBox5.Text = cnt1.ToString();//字数
textBox6.Text = cnt2.ToString();//字节数量(不含" ","\t","\n","\r"," ?")
textBox7.Text = cnt3.ToString();//数字数量
textBox8.Text = cnt4.ToString();//字母数量
textBox9.Text = (cnt2 - cnt1).ToString();//汉字数量
textBox10.Text = (cnt2 - cnt3 - cnt4 - (cnt2 - cnt1) * 2).ToString();//符号数量
}
}
}
}
//richTextBox1.text内容改变事件
private void richTextBox1_TextChanged(object sender, EventArgs e)
{
bool skipSpace = true;
int cnt1=0, cnt2=0, cnt3=0, cnt4=0;
if (this.richTextBox1.Text != null)
{

{

textBox8.Text = cnt4.ToString();//字母数量
textBox9.Text = (cnt2 - cnt1).ToString();//汉字数量
textBox10.Text = (cnt2 - cnt3 - cnt4 - (cnt2 - cnt1)*2).ToString();//符号数量
}
}
