进度条

一、主要实现的是输入进度条最大数，点开始进度条会往前加载，同时将日志存到文本框2里面去

二、编辑代码

 

namespace 进度条Again

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

            button1.Enabled = false;

            button2.Enabled = false;

            button3.Enabled = false;

        }

      

        private void button1_Click(object sender, EventArgs e)//开始按钮

        {   

            if(string.IsNullOrWhiteSpace(textBox1.Text))

            {

                return;

            }

            else

            {

                button2.Enabled = true;

                button3.Enabled = true;

                toolStripProgressBar1.Value = 0;//进度条当前值为0

                toolStripProgressBar1.Minimum = 0;//进度条最小值为0

                toolStripProgressBar1.Maximum = Convert.ToInt32(textBox1.Text);//进度条最大值为文本框1输入的数

                timer1.Enabled = true;

            }

        }



        private void textBox1_TextChanged(object sender, EventArgs e)//当文本框1文本改变的时候button1才可以用

        {

            button1.Enabled = true;

        }



        private void button2_Click(object sender, EventArgs e)//暂停

        {　　 
　　　　　　　button1.Enabled = false;

            if (button2.Text == "暂停")

            {

                timer1.Enabled = false;

                button2.Text = "继续";

                textBox2.AppendText(DateTime.Now.ToString("HH:mm:ss") + "进度暂停" + "\r\n");//AppendText追加文本

            }

            else

            {

                timer1.Enabled = true;

                button2.Text = "暂停";

                textBox2.AppendText(DateTime.Now.ToString("HH:mm:ss") + "进度继续" + "\r\n");

            }

            

        }



        private void button3_Click(object sender, EventArgs e)//停止

        {

            timer1.Enabled = false;

            toolStripProgressBar1.Value = 0;

            textBox2.Text = "";

            textBox1.Text = "";

            button1.Enabled = false;

            button2.Enabled = false;

            button3.Enabled = false;



        }



        private void timer1_Tick(object sender, EventArgs e)

        {

            if (toolStripProgressBar1.Value < toolStripProgressBar1.Maximum)//如果进度条当前的值小于进度条最大的值

            {

                toolStripProgressBar1.Value++;//就把进度条的当前值++

                textBox2.AppendText(DateTime.Now.ToString("HH:mm:ss") + "当前进度为[" + toolStripProgressBar1.Value + "/" + toolStripProgressBar1.Maximum + "]...." + "\r\n");//拼接字符串



            }

            else

            {

                textBox2.Text = "";

            }

        }



        private void button4_Click(object sender, EventArgs e)

        {

            this.Close();

        }

    }

}
