Hai sobat jufrikablog kali ini saya sedikit menjelaskan tentang contoh contoh penggunaan method dari string yang sangat beragam ada lower, upper , insert , remove, join , split dll , nah bagaimana cara membuatnya? cek sob
- Buat Desain seperti gambar diatas sob
- Gunakan fungsi fungsi yang bisa sobat download di modul praktikum ini
- nah buat kodingannya seperti source di bawah ini
using System;
using System.Collections.Generic;
using System.Drawing;
using System.Windows.Forms;
namespace latihan
{
public partial class MainForm : Form
{
//data 1
private string strText = “My String”;
//data 2
private string str = “My String is a long string”;
public MainForm()
{
InitializeComponent();
textBox1.Text = strText;
textBox10.Text = str;
}
//data 1
void insert(){
int a = Convert.ToInt16(textBox2.Text);
string b = Convert.ToString(textBox3.Text);
string test = strText.Insert(a, b) ;
textBox19.Text = test; }
void rem(){
int a = Convert.ToInt16(textBox4.Text);
int b = Convert.ToInt16(textBox5.Text);
string test = strText.Remove(a, b);
textBox20.Text = test;}
void lower(){
string test = strText.ToLower();
textBox17.Text = test;}
void upper(){
string test = strText.ToUpper();
textBox18.Text = test;}
void join(){
string a = Convert.ToString(textBox6.Text);
string b = Convert.ToString(textBox7.Text);
string c = Convert.ToString(textBox8.Text);
string[] d = { a, b };
string test = String.Join(c, d);
textBox21.Text = test;}
void split(){
string a = Convert.ToString(textBox9.Text);
string[] b = strText.Split();
textBox23.Text = string.Join(a, b);}
void trim(){
string test = strText.Trim();
textBox22.Text = test;}
//data 2
void io(){
string a = Convert.ToString(textBox11.Text);
int test = str.IndexOf(a);
string b = Convert.ToString(test);
textBox24.Text = b;}
void io2(){
string a = Convert.ToString(textBox12.Text);
int b = Convert.ToInt16(textBox13.Text);
int test = str.IndexOf(a, b);
string c = Convert.ToString(test);
textBox25.Text = c;}
void lio(){
string a = Convert.ToString(textBox14.Text);
int test = str.LastIndexOf(a);
string b = Convert.ToString(test);
textBox26.Text = b;}
void lio2(){
string a = Convert.ToString(textBox15.Text);
int b = Convert.ToInt16(textBox16.Text);
int test = str.LastIndexOf(a, b);
string c = Convert.ToString(test);
textBox27.Text = c;}
//button data 1
void Button3Click(object sender, EventArgs e)
{
insert();
}
void Button4Click(object sender, EventArgs e)
{

}
void Button1Click(object sender, EventArgs e)
{
lower();
}
void Button2Click(object sender, EventArgs e)
{
upper();
}
void Button5Click(object sender, EventArgs e)
{
join();
}
void Button7Click(object sender, EventArgs e)
{
split();
}
void Button6Click(object sender, EventArgs e)
{

}
//display data 2
void Button8Click(object sender, EventArgs e)
{

}
void Button9Click(object sender, EventArgs e)
{

}
void Button10Click(object sender, EventArgs e)
{

}
void Button11Click(object sender, EventArgs e)
{

}
//retry
void Button12Click(object sender, EventArgs e)
{
this.textBox2.Clear();
this.textBox3.Clear();

}
//exit
void Button16Click(object sender, EventArgs e)
{
this.Close();
}
}
}
- setelah itu runningkan dan jalankan , amati cobalah mengerti sob :D
