2、添加引用 System.Drawing;
3、添加资源文件(添加--新建项--资源文件),例如文件名为 Resource1.resx;
4、添加图片(打开Resource1.resx,单击“添加资源”后的小三角,选择添加现有文件,选择需要作为资源的图片),例如添加了图片 Sunset.jpg
5、添加类,例如名为 GetImage.cs
using
System;
namespace ResourcesLibrary
{
public class GetImage
{
public System.Drawing.Bitmap GetSunset()
{
return Resource1.Sunset;
}
}
}
6、UI层添加对类库的引用(ResourcesLibrary.dll)
namespace ResourcesLibrary
{
public class GetImage
{
public System.Drawing.Bitmap GetSunset()
{
return Resource1.Sunset;
}
}
}
7、添加aspx页面,例如名字为GetImage.aspx, Page_Load里添加如下代码
protected
void
Page_Load(
object
sender, EventArgs e)
{
ResourcesLibrary.GetImage img = new ResourcesLibrary.GetImage();
System.Drawing.Bitmap bmp = img.GetSunset();
System.IO.MemoryStream ms = new System.IO.MemoryStream();
try
{
bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
Response.ClearContent();
Response.ContentType = " image/Png " ;
Response.BinaryWrite(ms.ToArray());
}
finally
{
bmp.Dispose();
}
}
8、新建aspx页面,例如名字为ShowIamge.aspx,代码如下;
{
ResourcesLibrary.GetImage img = new ResourcesLibrary.GetImage();
System.Drawing.Bitmap bmp = img.GetSunset();
System.IO.MemoryStream ms = new System.IO.MemoryStream();
try
{
bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
Response.ClearContent();
Response.ContentType = " image/Png " ;
Response.BinaryWrite(ms.ToArray());
}
finally
{
bmp.Dispose();
}
}
