100分，把这段代码翻译成c#的

This function creates the Thumbnail image and returns the
image created in Byte() format
Private Function createThumnail()Function createThumnail(ByVal ImageStream As Stream,
ByVal tWidth As Double, ByVal tHeight As Double) As Byte()
Dim g As System.Drawing.Image =System.Drawing.Image.FromStream(ImageStream)
Dim thumbSize As New Size()
thumbSize =NewthumbSize(g.Width, g.Height, tWidth, tHeight)
Dim imgOutput As New Bitmap(g, thumbSize.Width, thumbSize.Height)
Dim imgStream As New MemoryStream()
Dim thisFormat = g.RawFormat
imgOutput.Save(imgStream, thisFormat)
Dim imgbin(imgStream.Length) As Byte
imgStream.Position = 0
Dim n As Int32 = imgStream.Read(imgbin, 0, imgbin.Length)
g.Dispose()
imgOutput.Dispose()
Return imgbin
End Function

Function NewthumbSize()Function NewthumbSize(ByVal currentwidth As Double, ByVal
currentheight As Double, ByVal newWidth As Double, ByVal newHeight As Double)
' Calculate the Size of the New image
Dim tempMultiplier As Double

If currentheight > currentwidth Then ' portrait
tempMultiplier = newHeight / currentheight
Else
tempMultiplier = newWidth / currentwidth
End If

End Function

楼主这段vb代码本身就有问题吧？本身错误怎么翻译啊？

你能不能帮忙该一下呀
源码在http://www.cnblogs.com/rippleyong/archive/2004/08/10/31977.aspx
我只要改变图片的大小的一些函数

这样试一下。只保证在C#的转换正确。不保证你的函数是否正确。
private byte[] createThumnail(Stream ImageStream,Double tWidth,Double tHeight)
{
System.Drawing.Image g = System.Drawing.Image.FromStream(ImageStream);
System.Drawing.Size thumbSize = new Size(g.Width, g.Height, tWidth, tHeight);
System.Drawing.Bitmap imgOutput = new Bitmap(g,thumSize.Width,thumSize.Height);
System.IO.MemoryStream imgStream = new MemoryStream();
System.Drawing.Imaging.ImageFormat thisFormat = g.RawFormat;
imgOutput.Save(imgStream, thisFormat);
byte[] imgbin = new byte[imgStream.Length];
imgStream.Position = 0;
int n = imgStream.Read(imgbin,0,imgbin.Length);
g.Dispose();
imgOutput.Dispose();
return imgbin;
}

public int NewthumbSize(Double currentwidth,Double currentheight,Double newWidth, Double newHeight)
{
Double tempMultiplier;
if(currentheight > currentwidth)
tempMultiplier = newHeight / currentheight;
else
tempMultiplier = newWidth / currentwidth;
System.Drawing.Size NewSize = new Size(Convert.ToInt32(currentwidth * tempMultiplier),Convert.ToInt32(currentheight * tempMultiplier));
return NewSize;
}

工具转的
private byte[] createThumnail(Stream ImageStream,Double tWidth,Double tHeight)
{
System.Drawing.Image g = System.Drawing.Image.FromStream(ImageStream);
System.Drawing.Size thumbSize = new Size(g.Width, g.Height, tWidth, tHeight);
System.Drawing.Bitmap imgOutput = new Bitmap(g,thumSize.Width,thumSize.Height);
System.IO.MemoryStream imgStream = new MemoryStream();
System.Drawing.Imaging.ImageFormat thisFormat = g.RawFormat;
imgOutput.Save(imgStream, thisFormat);
byte[] imgbin = new byte[imgStream.Length];
imgStream.Position = 0;
int n = imgStream.Read(imgbin,0,imgbin.Length);
g.Dispose();
imgOutput.Dispose();
return imgbin;
}

public int NewthumbSize(Double currentwidth,Double currentheight,Double newWidth, Double newHeight)
{
Double tempMultiplier;
if(currentheight > currentwidth)
tempMultiplier = newHeight / currentheight;
else
tempMultiplier = newWidth / currentwidth;
System.Drawing.Size NewSize = new Size(Convert.ToInt32(currentwidth * tempMultiplier),Convert.ToInt32(currentheight * tempMultiplier));
return NewSize;
}
