我似乎无法解析日期时间，例如
generic_list = []
for i in input:
if el in i:
generic_list.append(i)
number = len(generic_list)
if number>2:
input.something...
无论我添加哪种格式都行不通。这是我的代码：
"7/10/2019 2:52:52 PM".
答案 0 :(得分：5)
您应该将public class ComboBoxItemTemplateSelector : DataTemplateSelector
{
public DataTemplate Template1 { get; set; }
public DataTemplate Template2 { get; set; }
public override DataTemplate SelectTemplate(object item, DependencyObject container)
{
//Logic to select template based on 'item' value.
if (item == <template1Value>) return Template1; //TODO: replace <template1Value>
else if (item == <template2Value>) return Template2; //TODO: replace <template2Value>
else return new DataTemplate();
}
}
<local:ComboBoxItemTemplateSelector x:Key="ComboBoxItemTemplateSelector">
<local:ComboBoxItemTemplateSelector.Template1>
<DataTemplate>
<TextBlock Text="" />
</DataTemplate>
</local:ComboBoxItemTemplateSelector.Template1>
<local:ComboBoxItemTemplateSelector.Template2>
<DataTemplate>
<TextBlock Text="" />
</DataTemplate>
</local:ComboBoxItemTemplateSelector.Template2>
</local:ComboBoxItemTemplateSelector>
<ContentPresenter Content="{Binding NodeType}" ContentTemplateSelector="{StaticResource ComboBoxItemTemplateSelector}"/>
称为<DataTemplate>
<TextBlock Text="" DataContext="{Binding DataContext, RelativeSource={RelativeSource AncestorType=ContentPresenter}}"/>
</DataTemplate>
，并使用PM（而不是tt），因为小时是h格式，即
H
