您当前的位置: 方式一：
/// <summary>
/// 从程序集中加载图片
/// </summary>
/// <param name="imagePathName">图片路径（该图片必须是嵌入的资源）</param>
/// <returns>Bitmap 格式图片</returns>
public Bitmap GetIcon(string imagePathName)
{
Bitmap b = null;
try
{
Assembly asm1 = Assembly.GetExecutingAssembly();
string name = asm1.GetName().Name;
asm1.GetManifestResourceStream(imagePathName);
Stream imageStream = asm1.GetManifestResourceStream(imagePathName);
if (imageStream != null)
{
b = new Bitmap(Image.FromStream(imageStream));
b.MakeTransparent();
}
}
catch (Exception e)
{
throw new Exception(e.Message);
}
return b;
}
小注：
1、imagePathName= Assembly.GetExecutingAssembly().GetName().Name.ToString()+ ".Resources" + ".SelectCate.png";
2、图片要做为项目资源参与编译如下图：
方式二、
/// <summary>
/// 根据图片路径加载图片
/// </summary>
/// <param name="imagePathName">图片路径</param>
/// <returns>Bitmap格式图片</returns>
public Bitmap GetToolIcon(string imagePathName)
{
Bitmap b = null;
if (!File.Exists(imagePathName))
{
MessageBox.Show("该路径下：" + imagePathName.ToString() + "!文件找不到");
return b;
}
try
{
FileStream fs = new FileStream(imagePathName, FileMode.Open, FileAccess.Read);
b = (Bitmap)System.Drawing.Bitmap.FromStream(fs);
}
catch (Exception e)
{
throw new Exception(e.Message);
}
return b;
}
