问题描述
如何让文字不断显示在图片上？在Form1中添加了一个picturebox，在里面添加了一张图片，在程序运行过程中，会不断显示很多文本，如何让这些文本都显示在图片上方？而且还需要图片上方的文字加一个上下方向的滚动条，以查看显示的文字。我试过在picturebox上方加一个textbox，可是textbox不知道如何把它的背景色变为透明色，请大家帮帮忙，在线等，马上结贴！

解决方案二：
marque
解决方案三：
privatevoidpictureBox1_Paint(objectsender,PaintEventArgse){e.Graphics.DrawString("jinjazz",this.Font,Brushes.Red,newPointF(10,10));}
解决方案四：
这段代码是：有一个菜单file下子菜单为Open和Exit；一个OpenFileDialog1;打开一个txt文档，显示在界面上；可以达到你的要求，显示在背景图片之上，出现滚动条。usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Text;usingSystem.Windows.Forms;usingSystem.IO;usingSystem.Collections;namespaceCapsEditor{publicpartialclassForm1:Form{#regionConstantfieldsprivateconststringstandardTitle="CapsEditor";privateconstuintmargine=10;#endregion#regionMemberfieldsprivateArrayListdocumentLines=newArrayList();privateuintlineHeight;privateSizedocumentSize;privateuintnLines;privateFontmainFont;privateFontemptyDocumentFont;privateBrushmainBrush=Brushes.Blue;privateBrushemptyDocumentBrush=Brushes.Red;privatePointmouseDoubleClickPosition;privateOpenFileDialogfileOpenDialog=newOpenFileDialog();privatebooldocumentHasData=false;#endregionpublicForm1(){InitializeComponent();CreateFonts();fileOpenDialog.FileOk+=newCancelEventHandler(this.OpenFileDialog_FileOk);fileOpenDialog.Filter="Text(*.txt)|*.txt|C#(*.cs)|*.cs";}classTextLineInformation{publicstringText;publicuintWidth;}privatevoidCreateFonts(){mainFont=newFont("Arial",10);lineHeight=(uint)mainFont.Height;emptyDocumentFont=newFont("Verdana",13,FontStyle.Bold);}protectedvoidOpenFileDialog_FileOk(objectSender,CancelEventArgse){this.LoadFile(fileOpenDialog.FileName);}privatevoidmenuFileOpen_Click(objectsender,EventArgse){fileOpenDialog.ShowDialog();}privatevoidmenuExit_Click(objectsender,EventArgse){this.Close();}privatevoidLoadFile(stringFileName){StreamReadersr=newStreamReader(FileName);stringnextLine;documentLines.Clear();nLines=0;TextLineInformationnextLineInfo;while((nextLine=sr.ReadLine())!=null){nextLineInfo=newTextLineInformation();nextLineInfo.Text=nextLine;documentLines.Add(nextLineInfo);++nLines;}sr.Close();documentHasData=(nLines>0)?true:false;CalculateLineWidth();CalculateDocumentSize();this.Text=Form1.standardTitle+""+FileName;this.Invalidate();}privatevoidCalculateLineWidth(){Graphicsdc=this.CreateGraphics();foreach(TextLineInformationnextLineindocumentLines){nextLine.Width=(uint)dc.MeasureString(nextLine.Text,mainFont).Width;}}#regionCalculateDocumentSize函数privatevoidCalculateDocumentSize(){if(!documentHasData){documentSize=newSize(100,200);}else{documentSize.Height=(int)(nLines*lineHeight)+2*(int)margine;uintmaxLineLength=0;foreach(TextLineInformationnextWordindocumentLines){uinttempLineLength=nextWord.Width+2*margine;if(tempLineLength>maxLineLength){maxLineLength=tempLineLength;}documentSize.Width=(int)maxLineLength;}this.AutoScrollMinSize=documentSize;}}#endregion
