如何获得控件字体的默认值? [英] How do i get the default value of a control's font?

问题描述

我正在尝试获取控件字体的默认值，以便确定它当前是否为默认值.

i am trying to get the default value of a control's font so i can determine if it is currently the default value.

如何获取控件字体的默认值?

How do i get the default value of a control's font?

我尝试通过反射获取Font属性的DefaultValue属性:

i tried getting the DefaultValue attribute of the Font property through reflection:

// Gets the attributes for the property.
AttributeCollection attributes = TypeDescriptor.GetProperties(label1)["ForeColor"].Attributes;

//Find the "DefaultValue" attribute
DefaultValueAttribute myAttribute = (DefaultValueAttribute)attributes[typeof(DefaultValueAttribute)];

除了没有默认值属性(myAttribute 为空)

except there is no default value attribute (myAttribute is null)

然后我意识到有 AmbientValue 属性，这意味着属性的值来自控件的父级.

i then realized that there's the AmbientValue attribute, which means that the value of an attribute comes from a control's parent.

跟随一个控件的 control.Parent 链发现它们每个都有一个 AmbientValue 属性标签，一直到 Form.

Following a control up it's control.Parent chain finds each of them have an AmbientValue attribute tag, all the way up to Form.

• label1 [AmbientValue](无默认值)
  • form1 [AmbientValue](无默认值)
    • null
    • label1 [AmbientValue] (no DefaultValue)
      • form1 [AmbientValue] (no DefaultValue)
        • null

        那么如何获得控件的Font 属性的默认值?

        So how do i get the default value of a control's Font property?

        推荐答案

        如果您在谈论 WinForms，我认为 Control.DefaultFont 属性应该会有所帮助.

        If you're talking about WinForms, I figure the Control.DefaultFont property should help.
