谁能帮我编译一个标尺vc源代码改成c#语言源代码，100分相送

Question

在多文挡中的视图中声明一个
CRulerManager m_objRuler
对象。
在OnDraw()函数
加入m_objRuler.DrawRuler( pDC->m_hDC );
即可。头文件定义：//**************************************************************************************

Answer 1

请问一下C＃怎么调用VC创建的DLL文件呀，现在及用呀，谢谢位了

Answer 2

这个比较容易的，在C#里这样就可以了：
在FORM1里加个PANEL:
private void Form1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
{
System.Drawing.Graphics g=System.Drawing.Graphics.FromHwnd(this.panel1.Handle);
DrawRuler(g);
}//下面这个就是我改的函数
public void DrawRuler(System.Drawing.Graphics G)
{ System.Drawing.Rectangle rc=new Rectangle(100,0,10000,100);
System.Drawing.Rectangle rc1=new Rectangle(0,0,999,98);
System.Drawing.Rectangle rc20=new Rectangle(0,0,100,10000);
System.Drawing.Rectangle rc21=new Rectangle(0,0,97,9999); //画横向面板
G.DrawRectangle(new System.Drawing.Pen(System.Drawing.Color.Blue),rc);
 
G.FillRectangle(new System.Drawing.SolidBrush(System.Drawing.Color.Transparent),rc1);
//画纵向面板 G.DrawRectangle(new System.Drawing.Pen(System.Drawing.Color.Blue),rc20);
G.FillRectangle(new System.Drawing.SolidBrush(System.Drawing.Color.Transparent),rc21); //画横尺(X轴)
for(int i = 0; i < 10000; i++)
{
if((i%100) == 0 )
{
G.DrawLine(new System.Drawing.Pen(System.Drawing.Color.Blue),i+100, 0,i+100, 48);
G.DrawString((i/100).ToString(),new System.Drawing.Font(new System.Drawing.FontFamily(System.Drawing.Text.GenericFontFamilies.Serif),12),new System.Drawing.SolidBrush(System.Drawing.Color.Green),i+100-10, 50); } if((i%50) == 0)
{
  
G.DrawLine(new System.Drawing.Pen(System.Drawing.Color.Blue),i+100, 0,i+100, 32);
} if ( (i%10) == 0 )
{ G.DrawLine(new System.Drawing.Pen(System.Drawing.Color.Blue),i+100, 0,i+100, 16);
}        
}
//画纵尺(Y轴)
for(int  i = 0; i < 10000; i++)
{
if( (i%100) == 0 )
{
// pDC->MoveTo( 0, -i-100 );
// pDC->LineTo( 48, -i-100 );    
// pDC->TextOut( 50, -i-100+24, IntToStr(i/100));
G.DrawLine(new System.Drawing.Pen(System.Drawing.Color.Blue), 0, i,48, i);
G.DrawString((i/100).ToString(),new System.Drawing.Font(new System.Drawing.FontFamily(System.Drawing.Text.GenericFontFamilies.Serif),12),new System.Drawing.SolidBrush(System.Drawing.Color.Green), 50, i+100-24);
}
if( (i%50) == 0 )
{
// pDC->MoveTo( 0, -i-100 );
// pDC->LineTo( 32, -i-100 ); 
G.DrawLine(new System.Drawing.Pen(System.Drawing.Color.Blue),0, i,32, i);
} if( (i%10) == 0 )
{
// pDC->MoveTo( 0, -i-100 );
// pDC->LineTo( 16, -i-100 );
G.DrawLine(new System.Drawing.Pen(System.Drawing.Color.Blue),0, i ,16, i);
}
        
} //pDC->SelectObject( pOldFont ); //pDC->DeleteTempMap(); //::SetMapMode( hDC, oldMap );
//::RestoreDC( hDC, oldDC );    
}

真是谢谢了
调用dll文件可以通过引用方式，或者通过
[DllImport("KERNEL32.DLL", EntryPoint="MoveFileW",  SetLastError=true,
CharSet=CharSet.Unicode, ExactSpelling=true,
CallingConvention=CallingConvention.StdCall)]
public static extern bool MoveFile(String src, String dst);
