Bitmap bt=new Bitmap(stream),使用了无效的参数,why?

[heiguangbao]

你的stream 是什么/？

代码完整点

[cgsun]

在Northwind数据库里的Employees里的photo,就会包错,
但是对于pub数据库里的pub_info里的logo就不会包错.

[cgsun]

stream是ystem.IO.MemoryStream.
好象和社么"有题头的图象"有关,大家帮帮忙

[HNU]

你把代码贴出来撒～～

我也遇到这个问题了,不知道如何解决,

[cgsun]

System.IO.MemoryStream stream = new System.IO.MemoryStream();
System.IO.BinaryWriter writer = new System.IO.BinaryWriter(stream);
int BufferSize = 1024;
byte[] Buffer = new Byte[BufferSize];
long Offset = 0;
long BytesRead = 0;
do
{
BytesRead = dr.GetBytes(0, Offset, Buffer, 0, BufferSize);
writer.Write(Buffer, 0, (int)BytesRead);
Offset += BytesRead;
} while (BytesRead == BufferSize);

pictureBox1.Image=new Bitmap(stream);

改为
pictureBox1.Image=Image.FromStream(stream);

试试
