WPF使用心得

一、制作无边框窗体

XAML:

xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\" xmlns:x=\"http://schemas.microsoft.com/winfx/2006/xaml\"

Width=\"620\" Height=\"370\" WindowStyle=\"None\" AllowsTransparency=\"True\" MouseLeftButtonDown=\"DragWindow\">

CS：

using System;

using System.Collections.Generic; using System.Text;

using System.Windows;

using System.Windows.Controls; using System.Windows.Data;

using System.Windows.Documents;

using System.Windows.Input; using System.Windows.Media;

using System.Windows.Media.Imaging; using System.Windows.Shapes; using System.Data;

namespace Default.Window1 {

///

/// NetCrucialKpiDetail.xaml 的交互逻辑 ///

public partial class Window1: Window {

public Window1() {

InitializeComponent(); }

public void DragWindow(object sender, MouseButtonEventArgs args) {

this.DragMove(); }

public void CloseWindow(object sender, RoutedEventArgs args) {

this.Close(); } } }

二、ListView交替背景色

XAML:

Click=\"Btn_Workfollow_Click\" Tag=\"{Binding Path=ID}\" Background=\"Lavender\" FontWeight=\"Bold\">流程跟踪

新建一个类：BackgroundConverter.cs

using System;

using System.Collections.Generic; using System.Linq; using System.Text;

using System.Windows.Data; using System.Windows.Controls; using System.Windows.Media; using System.Globalization;

public sealed class BackgroundConverter : IValueConverter {

public object Convert(object value, Type targetType, object parameter, CultureInfo culture) {

ListViewItem item = (ListViewItem)value;

ListView listView = ItemsControl.ItemsControlFromItemContainer(item) as ListView;

// Get the index of a ListViewItem

int index = listView.ItemContainerGenerator.IndexFromContainer(item); if (index % 2 == 0) {

return Brushes.Moccasin; } else {

return Brushes.White; } }

public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) {

return null; } }

三、WPF中listview的全选、全不选

全选：listview.SelectAll();

全不选：listview.SelectedItems.Clear();

四、一个写日志的类

using System;

using System.Collections.Generic; using System.Linq; using System.Text; using System.IO;

public class Log {

//存放日志文件的文件夹名称

private const string tempFilename = \"ServiceLog\";

//filename 日志文件名 text要写入日志的文本 public static void WriteLine(string filename, string text) {

lock (typeof(Log)) {

try {

//存放日志文件夹的全路径

string file = String.Format(@\"C:\\Temp\\{0}\\\

Directory.CreateDirectory(file);

file = String.Format(\"{0}{1}.log\

if (File.Exists(file) && (new FileInfo(file)).Length > 5 * 1024 * 1024) {

string newFile = file.Remove(file.Length - 4, 4) + \"_bak.log\"; File.Copy(file, newFile, true); File.Delete(file); }

using (StreamWriter sw = new StreamWriter(file, true, Encoding.Unicode)) {

sw.WriteLine(String.Format(\"[{0}] \DateTime.Now.ToString(\"yyyy-MM-dd HH:mm:ss\")) + text); sw.Flush(); } } catch {

} } } }
