【c#】如何编写当鼠标点击PictureBox控件是时候切换多张图片
多次单击按钮button，可以按照一定的顺序变换着显示图片，所显示的所有图片都只在一个picturebox里显示，所设定的最后一张图片显示完后会回到第一张图片应当用怎样的语法编写？witch?if?函数提示：private void button1_Click(object sender, EventArgs e)｛Bitmap 图 = new Bitmap(@"图片地址");。。。。。。｝
把一楼的哥们东西改一下给你
private readonly List<string> imageList = new List<string>
{
//三张图片的地址
@"e:\1.jpg",
@"e:\2.jpg",
@"e:\3.jpg"
};
public int currIndex=0;//索引值
private void button1_Click(object sender, EventArgs e)
｛
if (currIndex >= imageList.Count)
{
currIndex = 0;
}
pictureBox1.Image = Image.FromFile(imageList[currIndex],true);
currIndex += 1;
｝
这代码应该直接可以用
private readonly List<string> imageList = new List<string>
{
//三张图片的地址
@"e:\1.jpg",
@"e:\2.jpg",
@"e:\3.jpg"
};
public int currIndex=0;//索引值
private void button1_Click(object sender, EventArgs e)
｛
if (currIndex >= imageList.Count)
{
currIndex = 0;
}
pictureBox1.Image = Image.FromFile(imageList[currIndex],true);
currIndex += 1;
｝
这代码应该直接可以用

给出代码
public partial class Form1 : Form
{
private readonly List<string> imageList = new List<string>
{
@"e:\1.jpg",
@"e:\2.jpg",
@"e:\3.jpg"
};
private int currIndex = 0;
public Form1()
{
InitializeComponent();
}
private void pictureBox1_Click(object sender, EventArgs e)
{
if (currIndex >= imageList.Count)
currIndex = 0;
pictureBox1.Image = Image.FromFile(imageList[currIndex],true);
currIndex += 1;
}
}追问
public partial class Form1 : Form
{
private readonly List<string> imageList = new List<string>
{
@"e:\1.jpg",
@"e:\2.jpg",
@"e:\3.jpg"
};
private int currIndex = 0;
public Form1()
{
InitializeComponent();
}
private void pictureBox1_Click(object sender, EventArgs e)
{
if (currIndex >= imageList.Count)
currIndex = 0;
pictureBox1.Image = Image.FromFile(imageList[currIndex],true);
currIndex += 1;
}
}追问
你可能没懂我的补充内容。。。我是说点击button变换图片。。。是不是把pictureBox1_Click改为button1_Click就可以了？

使用imagelist 在按钮事件中写
this.pictureBox1.Image = this.imageList1.Images[i];
改变i就可以了 判断如果i最大了就设置为0
this.pictureBox1.Image = this.imageList1.Images[i];
改变i就可以了 判断如果i最大了就设置为0
