不能在列表框中设置标签的颜色为什么？ [英] cant set color of label in listbox why?

问题描述

 System.Windows.Forms.Label lbl = new System.Windows.Forms.Label（）; 
 
 lbl.ForeColor = System.Drawing.Color.Blue; 
 
 string txt =+==++文件夹标题：++ sub ++ siteColName +; 
 var display = lbl.Text = txt.ToString（）; 
 listboxLogging.Items.Add（display + Environment.NewLine）; 

解决方案

你没有把标签加入在列表框中，您将文本放入列表框。



文本没有颜色概念。



设置列表框中项目的颜色实际上非常困难 - 您可以使用ListView。添加完项目后，您可以更改该项目的属性（项目的NB，而不是文本）



或者如果你真的想要使用您可以自己绘制颜色的列表框 - 查看一些建议此处 [ ^

System.Windows.Forms.Label lbl = new System.Windows.Forms.Label();
                                                    
lbl.ForeColor = System.Drawing.Color.Blue;

string txt = " " + "==" + " " + "Folders title:" + " " + sub + " " +  siteColName + " ";
var display= lbl.Text = txt.ToString();
listboxLogging.Items.Add( display + Environment.NewLine);

解决方案

You are not putting the label "into" the listbox, you are putting the text into the list box.

Text does not have a concept of colour.

It's actually quite difficult to set the colour of items in a listbox - you could use a ListView instead. Once you have added the item you can change the properties of that item (NB of the item, not the "text")

Or if you really want to use a Listbox you can "draw" the colour yourself - see some suggestions here[^]
