上には2つのカスタムタイプ変換器があります
XAMLドキュメントでの参照は次のとおりです.
一:DateTimeConverter変換器の使用
1：
xmlns:local="clr-namespace:KX_EHR"
>
2：
<
UserControl.Resources
>
<
local:DateTimeConverter
x:Key
="DateConverter"
/>
</
UserControl.Resources
>
3：
<
TextBlock
Text
="
{Binding Uoperatedate, Converter={StaticResource DateConverter}}
"
/>
二:ConvtoBSfcodeToStr変換器の使用
1：
xmlns:localConv="clr-namespace:KX_EHR.Class"
>
2：
<
UserControl.Resources
>
<
localConv:ConvtoBSfcodeToStr
x:Key
="ConverBStoStr"
/>
</
UserControl.Resources
>
3：
<
TextBlock
Text
="
{Binding ,Converter={StaticResource ConverBStoStr}}
"
/>
