C#与vb.net源码代码互转网站

该转换器是印度开发团队推出的，推出时间也挺长，仅支持C#和VB.net代码转换。
代码转换地址： C# -> VB.NET  http://www.dotnetspider.com/convert/Csharp-To-Vb.aspx

网站很不错  转成c#源码不错

这个是强制转换 代码

Dim temp As Byte = CByte((srcColor.R * 0.299 + srcColor.G * 0.587 + srcColor.B * 0.114))

' //设置像素的ＲＧＢ颜色值
srcBitmap.SetPixel(x, y, Color.FromArgb(temp, temp, temp))
Next
Next

Return srcBitmap
End Function
