现在只要是有关头像的框基本都是圆形的了，C#提供的PictureBox控键默认情况下是方形的非常大的影响美观
PictureBox默认情况下
窗体加载时：
pictureBox1.Image = Image.FromFile(@"C:\Users\Administrator\Desktop\1.png");
为了方便演示，在窗口加载的时候加载出图片
图片加载出来后然后，把框框变圆的
GraphicsPath gp = new GraphicsPath();
gp.AddEllipse(pictureBox1.ClientRectangle);
Region region = new Region(gp);
pictureBox1.Region = region;//赋值
gp.Dispose();//释放资源
region.Dispose();//释放资源
只有简单的几行
效果图：
一下美观了很多
接下来演示从数据库读取图片到框框上：
同样也是，写在窗口的加载事件
GraphicsPath gp = new GraphicsPath();
gp.AddEllipse(pictureBox1.ClientRectangle);
Region region = new Region(gp);
pictureBox1.Region = region;
gp.Dispose();
region.Dispose();
CheckForIllegalCrossThreadCalls = false;
username.Text = 登录界面.jmuser;
Thread th = new Thread(a);
th.IsBackground = true;
th.Start();
us = username.Text;
首页 form = new 首页();
form.TopLevel = false;
form.Parent = panel1;
panel1.Controls.Add(form);//将子窗体载入panel
form.Show();
SqlConnectionStringBuilder bu = new SqlConnectionStringBuilder();
bu.Password = "0";
bu.UserID =<i style="color:transparent">本文来源gaodai$ma#com搞$代*码6网</i> "0";
bu.DataSource = "0-0";
bu.InitialCatalog = "0";
SqlConnection b = new SqlConnection(bu.ToString());
string str = "select * from user1 where username ='" + 登录成功界面.us + "'";
b.Open();
SqlCommand c = new SqlCommand(str, b);
SqlDataReader d = c.ExecuteReader();
while (d.Read())
{
// label2.Text = d["userid"].ToString();
string s = d["头像"].ToString();
byte[] imageBytes = Convert.FromBase64String(s);
MemoryStream memoryStream = new MemoryStream(imageBytes, 0, imageBytes.Length);
memoryStream.Write(imageBytes, 0, imageBytes.Length);
Image image = Image.FromStream(memoryStream);
this.pictureBox1.SizeMode = PictureBoxSizeMode.Zoom;
this.pictureBox1.Image = image;
}
}
