C# 在C中读写ListView的简单方法？
是否有一种简单/标准的方法可以将文件读入listview并将其保存到文件中？我真的不在乎它是TXT文件、XAML文件还是二进制文件。这并不重要，我也没有那么多数据 以下是存储在每个数据库中的列和数据C# 在C中读写ListView的简单方法？,c#,wpf,file,listview,io,C#,Wpf,File,Listview,Io,是否有一种简单/标准的方法可以将文件读入listview并将其保存到文件中？我真的不在乎它是TXT文件、XAML文件还是二进制文件。这并不重要，我也没有那么多数据 以下是存储在每个数据库中的列和数据 public class LVData { public string Name { get; set; } public string YoungPic { get; set; } public string MediumPic {

自从使用这个屏幕上限后，我还添加了一个“加载”按钮。我编写了一个小项目，从XML读取数据并在列表视图中显示 下面是示例XML文件
<?xml version="1.0" encoding="utf-8"?>
<Persons>
<Person>
<Name>Dave</Name>
<YoungPic>Picture1</YoungPic>
<MediumPic>Picture2</MediumPic>

PropertyChanged(this, new PropertyChangedEventArgs(PropertyName));
}
}
private ObservableCollection<LVData> _personList = new ObservableCollection<LVData>();
public ObservableCollection<LVData> lsvData
{
get { return _personList; }
set { _personList = value; RaisePropertyChanged("lsvData"); }
}
public void PopulateDataFromXML()
{
XDocument loaded = XDocument.Load(@"c:\documents and settings\bjasti\my documents\visual studio 2010\Projects\lvs\lvs\data.xml");
var Persons = from x in loaded.Descendants("Person")
select new
{

};
foreach (var _person in Persons)
{
_personList.Add(new LVData { Name = _person.Name, YoungPic = _person.YoungPic, MediumPic = _person.MediumPic, AdultPic = _person.AdultPic, Terrain = Convert.ToByte(_person.Terrain) });

检查此解决方案并让我知道它是否有效您可以直接绑定到xml文件：这样您就不必手动将其复制到您的文件中，您只需保存此文件。什么？？你的问题完全不清楚。是的，您可以将数据存储在任何您想要的数据存储中，而这本身与WPF或任何表示层/UI元素/任何内容都没有任何关系。很抱歉不清楚。我感到困惑的是，如何将listview中的每个项目写入一个文件，然后将其读回？是否有一种“标准”的方法来做到这一点？我想我可以将每一行作为字符串转储到一个txt文件中，然后反转加载过程。我在找更优雅的东西。找不到这样做的示例或任何迹象。第一：感谢所有帮助！我快拿到了。我不得不更改地形数据。它现在是一系列复选框的布尔：公共类LVData{-snip-public bool SaltWater{get；set；}公共布尔淡水{get；set；}公共布尔草地{get；set；}公共布尔沼泽{get；set；}公共布尔热带雨林{get；set；}public bool-Forest{get；set；}public bool-ForestEdge{get；set；}-etc.-}这将如何更改您的代码？复选框是否相互排斥？不，复选框不是相互排斥的。这些是针对植物的，植物的“类型”可以在不同的地形中。您可以为每个工厂检查任意多个地形类型。仅供参考：这里有一个指向整个项目的链接：如何从XAML设置复选框？如何绑定所有地形类型复选框？此外，现在显示的是图像名称的文件字符串，而不是图像。我需要改变什么？
