c# 读取xml文件 编写form

主要思想:xml保存控件的数据,c#读取出来并加以显示。

难点:1.控件有父容器和子控件的关系;2.控件事件的添加。

1.控件有父容器和子控件的关系:

  可以用绝对坐标在xml文件中先读取子控件再读取父容器;

  也可以在子控件属性中设置一个标签记录父容器,然后c#读取时候父容器add子控件。

2.控件事件的添加:

  在控件add完之后也可以对事件进行添加(包括属性更改)。

  为了精确确定某个控件,c#读取到的诸多控件,不建议采用数组包装,用dictionnary省力。

代码:

xml文件:

<?xml version='1.0' encoding='UTF-8'?>
<XmlDataForm Name="ReportSum" Text="报告模板总" ClientSize="1086,1058" DataEntity="">
<Controls>
<Button name="button_firstLang" Location="51,32" Size="38,28" Text="CN" />
<Button name="button_secondLang" Location="96,32" Size="38,28" Text="EN" />
<GroupBox name="groupBox2" Location="188,12" Size="854,58" Text="采图信息" />
<Label name="label1" Location="68,24" Size="32,17" Text="姓名" />
<TextBox name="textBox_name" Location="103,21" Size="120,23" Text="" />
<Label name="label2" Location="229,24" Size="32,17" Text="性别" />
<ComboBox name="comboBox_sex" Location="263,21" Size="45,25" Text="" />
<Label name="label3" Location="313,24" Size="32,17" Text="年龄" />
<TextBox name="textBox_age" Location="348,21" Size="28,23" Text="" />
<Label name="label5" Location="417,24" Size="56,17" Text="采图站点" />
<TextBox name="textBox_site" Location="476,21" Size="92,23" Text="" />
<Label name="label6" Location="572,24" Size="60,17" Text="" />
<TextBox name="textBox_create_date" Location="635,21" Size="137,23" Text="" />
</Controls>
</XmlDataForm>
