C#WinForm ListBox设置文字颜色

• 给ListBox的DrawItem方法绑定事件 drawLog

  • //给ListBox的DrawItem事件绑定一个方法，取名drawProcessInfo
    LB_ProcessInfo.DrawItem += new DrawItemEventHandler(drawProcessInfo);

     
• 定义drawProcessInfo方法

  • {
                if (LB_ProcessInfo.Items.Count > 0 && LB_ProcessInfo.Items.Count > e.Index)
                {
                    if (e.Index < 0)
                    { return; }
                    string str = LB_ProcessInfo.Items[e.Index].ToString();
    
                    Color foreColor = Color.Black;
                    //重点，根据item的具体内容决定颜色
                    //if (str.Contains("本次测试PASS")) { foreColor = Color.Green; }
                    if (str.Contains("异常")) { foreColor = Color.Red; }
                    if (str.Contains("Message")) { foreColor = Color.Red; }
                    if (str.Contains("失败")) { foreColor = Color.Red; }
                    if (str.Contains("重新启动软件")) { foreColor = Color.Red; }
                    //重点，画上颜色
                    e.Graphics.DrawString(str, e.Font, new SolidBrush(foreColor), e.Bounds);
                }
            }

• ListBox的 DrawMode属性设置为 OwnerDrawFixed或者OwnerDrawVariable，才能让DrawItem事件触发
• 效果如下：
