Label控件是没有办法实现多种颜色的文字的,只能用RichTextBox来实现,而且你的自定义格式字符串也没有结尾的,这样很不好,至少也要<red>红色字</red><yellow>黄色字</yellow>,而且实现也很麻烦的,下面的代码我没有检测正确性,有错误的自己改一改吧
Dim colortag() as string
dim colors() as color
const txt as string="<red>红色字</red><yellow>黄色字</yellow>"
private sub Form_Load(object sender,eventargs e)handles mybase.load
colortag(0)="red":Colortag(1)="yellow"
colors(0)=color.red:colors(1)=color.yellow
richtextbox1.text=txt
for i as integer=0 to colortag.lenght-1
dim tag as string="<" & colortag(i) & ">"
dim endtag as string="</" & colortag(i) & ">"
dim find as integer=1
do
find=instr(find,txt,tag)+tag.lenght
if(find<>0)then
dim find1 as integer=instr(find,txt,endtag)
richtextbox1.SelectionStart=find
richtextbox1.selectionlenght=find1-find
richtextb
