读取txt文件加DevExpress之进度条progressBarControl

进度条使用 主要掌握下边几个命令,

 //水平进度条
progressBarControlH.Properties.Minimum = 0;
//1:设置最大数量,比如读取txt文件内容,先要查出行数,然后给maxinum赋值,此处是进度条的最大容量.
progressBarControlH.Properties.Maximum = 100;
//2: 进度条的进度,读取一行,内部自动计算的
   while (sr.Peek() > -)
{
line = sr.ReadLine().ToString().Replace("\r\n", "");
//跳过行空格
if (line.Trim() != "")
{
// progressBarControlH.Text = "开始过滤字段生成文件....."; // System.Threading.Thread.Sleep(120);
progressBarControlH.PerformStep();
// progressBarControlH.Position += 1;
// progressBarControlH.EditValue = i + 1;
//处理当前消息队列中的所有windows消息,不然进度条会不同步
System.Windows.Forms.Application.DoEvents();
......................}

下边是所有的步骤,

1:初始化进度条 ,最大值等查完txt行数赋值.

    private void panelControl1_Paint(object sender, PaintEventArgs e)
{
//水平进度条
progressBarControlH.Properties.Minimum = ;
//progressBarControlH.Properties.Maximum = 2000000;
progressBarControlH.Properties.Step = ;
progressBarControlH.Properties.ProgressViewStyle = DevExpress.XtraEditors.Controls.ProgressViewStyle.Solid;
progressBarControlH.Position = ;
progressBarControlH.Properties.ShowTitle = true;
progressBarControlH.Properties.PercentView = true;
progressBarControlH.Properties.ProgressKind = DevExpress.XtraEditors.Controls.ProgressKind.Horizontal;
}

2:读取text行数

    int CalculateCount(string filepath)
{
//定义一个变量
int lineCount = ;
//文件路径
// string path = @"D:\SQL.txt";
try
{
using (StreamReader sr = new StreamReader(filepath))
{
//循环读取
while (sr.Peek() >= )
{
sr.ReadLine();
lineCount++;
}
}
return lineCount;
// this.label1.Text = "文件行数为:" + lineCount.ToString();
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
return ;
}
}

3:赋值进度条最大值,并开始统计进度

   int count= CalculateCount(file);
lblcount.Visible = true;
lblcount.Text = count.ToString();
progressBarControlH.Properties.Maximum = count;
//删除后缀 存入files类Filename属性 ,后用于存在word第一行
StreamReader sr = new StreamReader(file, System.Text.Encoding.Default);
// filecontents = new Queue<FileContent>();
String line;
// while (sr.EndOfStream!=true)
StringBuilder sb = new StringBuilder();
while (sr.Peek() > -)
{
line = sr.ReadLine().ToString().Replace("\r\n", "");
//跳过行空格
if (line.Trim() != "")
{
// progressBarControlH.Text = "开始过滤字段生成文件....."; // System.Threading.Thread.Sleep(120);
progressBarControlH.PerformStep(); // progressBarControlH.Position += 1;
// progressBarControlH.EditValue = i + 1;
//处理当前消息队列中的所有windows消息,不然进度条会不同步
System.Windows.Forms.Application.DoEvents();

progressBarControl和marqueeProgressBarControl

一.progressBarControl

progressBarControl是一个进度条控件

几个重要参数

Minimum------------------进度最小数值

Maximum-----------------进度最大数值

Step----------------------每走一步的数值

Position ------------------当前值

EditValue-----------------编辑值

ProgressViewStyle--------样式(其实我没看出什么区别)

ShowTitle-----------------是否显示标题(没有设置显示百分比的时候一般显示value值)

PercentView---------------是否显示百分比(需要ShowTitle为true)

ProgressKind-------------进度条方向(横向/纵向),这只是进度的显示方向,具体控件还要自己把它拉成横向或者纵向

TextOrientation-----------进度条文本显示方向(横向/纵向)

方法

PerformStep() -----------进度条前进一步

添加两个进度条,一个横向,一个纵向,并初始化一下参数

读取txt文件加DevExpress之进度条progressBarControl
            //水平进度条
progressBarControlH.Properties.Minimum = 0;
progressBarControlH.Properties.Maximum = 100;
progressBarControlH.Properties.Step = 1;
progressBarControlH.Properties.ProgressViewStyle = DevExpress.XtraEditors.Controls.ProgressViewStyle.Solid;
progressBarControlH.Position = 0;
progressBarControlH.Properties.ShowTitle = true;
progressBarControlH.Properties.PercentView = true;
progressBarControlH.Properties.ProgressKind = DevExpress.XtraEditors.Controls.ProgressKind.Horizontal; //垂直进度条
progressBarControlV.Properties.Minimum = 0;
progressBarControlV.Properties.Maximum = 100;
progressBarControlV.Properties.Step = 1;
progressBarControlV.Properties.ProgressViewStyle = DevExpress.XtraEditors.Controls.ProgressViewStyle.Solid;
progressBarControlV.Position = 0;
progressBarControlV.Properties.ShowTitle = true;
progressBarControlV.Properties.PercentView = true;
progressBarControlV.Properties.ProgressKind = DevExpress.XtraEditors.Controls.ProgressKind.Vertical;
progressBarControlV.Properties.TextOrientation = DevExpress.Utils.Drawing.TextOrientation.Horizontal;

当把进度条设置为纵向的时候一般需要Title或者百分比的显示还是横向的,这样看起来才舒服,所以要设置一下TextOrientation属性

调用代码:

读取txt文件加DevExpress之进度条progressBarControl
            for (int i = 0; i < 100; i++)
{ System.Threading.Thread.Sleep(120);
progressBarControlH.PerformStep();
progressBarControlV.PerformStep();
//progressBarControl1.Position +=1;
//progressBarControl1.EditValue = i + 1;
//处理当前消息队列中的所有windows消息,不然进度条会不同步
System.Windows.Forms.Application.DoEvents();
}
progressBarControlH.EditValue = 0;
progressBarControlV.EditValue = 0;

让进度条移动有三种方式

1.改变Position的值

2.改变EditValue的值

3.用PerformStep方法

不过要注意的是,这三种方式后面都要加上System.Windows.Forms.Application.DoEvents(),就是每次改变进度的时候都要让windows处理当前队列的消息,以确保进度条同步,否则可能出现进度条的数据更改了,可是进度没有动的情况

二.marqueeProgressBarControl

marqueeProgressBarControl用起来比较简单,但是没有ProgressBarControl的显示进度和百分比的功能

读取txt文件加DevExpress之进度条progressBarControl
       marqueeProgressBarControlH.Properties.ProgressKind = DevExpress.XtraEditors.Controls.ProgressKind.Horizontal;
marqueeProgressBarControlH.Properties.ShowTitle = true;
marqueeProgressBarControlH.Text = "横向读取数据中,请稍等。。。。"; marqueeProgressBarControlV.Properties.ProgressKind = DevExpress.XtraEditors.Controls.ProgressKind.Vertical;
marqueeProgressBarControlV.Properties.ShowTitle = true;
marqueeProgressBarControlV.Text = "纵向数据读取中,请稍等";
marqueeProgressBarControlV.Properties.TextOrientation = DevExpress.Utils.Drawing.TextOrientation.VerticalUpwards;
