C# 。如果(图像 == Properties.Resources.image)

Question

我想对一张图片做一个 if 语句

          if (SortName.Image == Properties.Resources.RadioEmpty)
          {
              SortName.Image = Properties.Resources.Radio;
          }
          else
          {
              SortName.Image = Properties.Resources.RadioEmpty;
          }

但是它在工作时知道我做错了什么吗？好的附加信息

1.

          //SortName = A picture box
          //Properties.Resources.RadioEmpty = Resources\RadioEmpty.png
          //Properties.Resources.Radio = Resources\Radio.png

2。不，没有错误

3.我想为单选按钮使用自定义图像。单击时有一个带有上述代码的图片框。 RadioEmpty 是默认设置，因此我检查图片框的图像是否与 Resources 文件夹中的图像相同，代码也是如此。

我建议您使用标签来解决这个问题，请参阅此代码

  private void Form1_Load(object sender, EventArgs e)
        {
            //in form load the radio is checked or unckecked
            //here my radio is unchecked at load
            pictureBox1.Image = WindowsFormsApplication5.Properties.Resources.Add;
            pictureBox1.Tag = "UnChecked";
        }

   private void pictureBox1_Click(object sender, EventArgs e)
        {
            //after pictiurebox clicked change the image and tag too
            if (pictureBox1.Tag.ToString() == "Checked")
            {
                pictureBox1.Image = WinFormsApplication.Properties.Resources.Add;
                pictureBox1.Tag = "UnChecked";
            }
            else
            {
                pictureBox1.Image = WinFormsApplication.Properties.Resources.Delete;
                pictureBox1.Tag = "Checked";
            }
        }
