WPF数据对象的绑定及转换

一、WPF DataGrid数据的绑定

(1)列类型为DataGridCheckBoxColumn时，可绑定一个bool型变量，实现CheckBox是否选中


private bool _isUse;
public bool IsUse
{
get { return _isUse; }
set
{
_isUse = value;
RaiseProperChanged();
}
}

public event PropertyChangedEventHandler PropertyChanged;
private void RaiseProperChanged([CallerMemberName] string caller = "")
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(caller));
}
}


(2)列类型为DataGridComboBoxColumn时，可绑定列表，实现下拉列表的选择


public List GetParasList()
{
List result = new List();
result.Add("=");
result.Add(">");
result.Add("<");
result.Add("≥");
result.Add("≤");
return result;
}


二、数据列表的序列化与反序列化

(1)序列化保存


public static void XmlSerialize(T obj,string path)
{
try
{
XmlSerializer serializer = new XmlSerializer(obj.GetType());
TextWriter tw = new StreamWriter(path);
serializer.Serialize(tw, obj);
tw.Close();
}
catch(Exception ex)
{
}
}


(2)反序列化加载


public static object XmlDserialize(Type t,string path)
{
try
{
using(FileStream fs = new FileStream(path,FileMode.Open))
{
XmlSerializer serializer = new XmlSerializer(t);
return serializer.Deserialize(fs);
}
}
catch (Exception ex)
{
return null;
}
}


测试


//保存
XmlSerializeTool.XmlSerialize(mAllData,path);
//读取
mAllData= XmlSerializeTool.XmlDserialize(mAllData.GetType(), path) as ObservableCollection;
