A. 关于ASP.net 向客户端输出文件的问题
这是我做过的一个下载页面，不会另打开一个页面，也不会刷新，它用Response.Write直接向前台输出二进制。源文件代码在这里，你应该看得懂吧。需要的命名空间，请你在VS的智能提示下补充上去。string strPhyPath = Server.MapPath("~/")+ fileurl;//fileurl是文件的相对地址if (File.Exists(strPhyPath)){ //取文件大小 FileStream MyFileStream; uint FileSize1; MyFileStream = new FileStream(strPhyPath, FileMode.Open, FileAccess.Read, FileShare.None); int iConverTemp = Convert.ToInt32(MyFileStream.Length); FileSize1 = (uint)(iConverTemp); MyFileStream.Close(); //存在,下载 Page.Response.ContentType = "APPLICATION/OCTET-STREAM"; Page.Response.AddHeader("Content-length", FileSize1.ToString());//下载文件长度 Page.Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(strPhyPath, System.Text.Encoding.UTF8)); Page.Response.WriteFile(strPhyPath); Response.Flush(); Response.End();}else{ this.Alert("文件不存在，请及时向管理员反馈!");//Alert是我自定义定义的方法}
B. 在vb.net中如何生成一个txt文件，并且写入一个数组的值
已测试，代码如下：
ImportsSystem.IO'引入文本操作
PublicClassForm1
PrivateSubButton1_Click(ByValsenderAsSystem.Object,ByValeAsSystem.EventArgs)HandlesButton1.Click
DimtxtAsString=Me.getTxt
SaveTxt(txt)
EndSub
'取得存储的文本
PrivateFunctiongetTxt()AsString
Dimx(0To10)AsInteger
ForiAsInteger=0Tox.Length-1
x(i)=CInt(100*Rnd())
Next
DimstrAsString=""
ForjAsInteger=0Tox.Length-1
str+=x(j).ToString&vbCrLf
Next
Returnstr
EndFunction
'存储文本
PrivateSubSaveTxt(ByValvAsString)
DimfpAsString=GetSavePath()
IfString.IsNullOrEmpty(fp)=FalseThen
'StreamWriter
DimSwriterAsNewStreamWriter(fp,False)'覆盖或新建
Swriter.WriteLine(v)
Swriter.Close()
EndIf
EndSub
'取得存储路径
PrivateFunctionGetSavePath()AsString
sd.FileName=""
sd.AddExtension=True
sd.DefaultExt="txt"
sd.Filter="TXT文件(*.txt)|*.txt"
sd.ShowDialog()
Returnsd.FileName
EndFunction
EndClass
测试截图如下。
C. 我要用C#,NET 导出一个word文档。文档内容只要一个表格。
楼上的 你能不能改写下这个例子啊？ 我这个只能导出字符 不能导出表格 string title = "个人信息"; object titleLengh = title.Length; string first = "\n 公司最近需要利用C#对项目进行编程,其" + "中存在一个功能就是可自动生成WORD文档,但一直以来都" + "找不到什么好办法,无奈之下,只有自已学着写一个了."; object firstLengh = first.Length; string second = "\n 如果能真正生成WORD文档的好处有:"; object secondLengh = second.Length; string third = "\n1、根据数据库信息自动生成文档；"; object thirdLengh = third.Length; string forth = "\n2、免去书写文档之苦；"; object forthLengh = forth.Length; string fifth = "\n3、可以通过邮件方式传出文档。"; object fifthLengh = fifth.Length; object missing; object zero = 0; object c = 10; object one = 1; object two = 2; object tree = 3; object four = 4; object five = 5; object six = 6; object seven = 7; object eight = 8; object nine = 9; object ten = 10; Object Nothing = System.Reflection.Missing.Value; Microsoft.Office.Interop.Word.ApplicationClass wa = new Microsoft.Office.Interop.Word.ApplicationClass(); Microsoft.Office.Interop.Word.Document WordDoc = wa.Documents.Add(ref Nothing, ref Nothing, ref Nothing, ref Nothing); missing = System.Reflection.Missing.Value; wa.Visible = true; wa.Documents.Add(ref missing, ref missing, ref missing, ref missing); Microsoft.Office.Interop.Word.Range myRange = wa.ActiveDocument.Range(ref zero, ref zero); object r = myRange; Microsoft.Office.Interop.Word.Paragraph p = wa.ActiveDocument.Paragraphs.Add(ref r); p.Range.InsertBefore(title); //p.Range.Font.Size = 1;Microsoft.Office.Interop.Word.Range titleRange = wa.ActiveDocument.Range(ref zero, ref titleLengh); //titleRange.Font.Size = 1; titleRange.Font.Name = "幼圆"; titleRange.Font.Color = Microsoft.Office.Interop.Word.WdColor.wdColorBlue; //MessageBox.Show("NO.1"); //titleRange.Paragraphs.Alignment = Microsoft.Office.Interop.Word.WdParagraphAlignment.wdAlignParagraphRight; Microsoft.Office.Interop.Word.Range firstR = wa.ActiveDocument.Paragraphs[1].Range;//.Item(2).Range; Microsoft.Office.Interop.Word.Table table = WordDoc.Tables.Add(titleRange, 3, 3, ref Nothing, ref Nothing); r = firstR; p = wa.ActiveDocument.Paragraphs.Add(ref r);firstR.Font.Size = 40; firstR.Paragraphs.Alignment = Microsoft.Office.Interop.Word.WdParagraphAlignment.wdAlignParagraphCenter;//在表格第一单元格中添加自定义的文字内容 table.Cell(1, 1).Range.Text = "lllll";firstR.InsertAfter(first);//firstR.InsertParagraphAfter(); //firstR=wa.ActiveDocument.Paragraphs.Item(3).Range; firstR.InsertAfter(second); firstR.InsertAfter(third); firstR.InsertAfter(forth); firstR.InsertAfter(fifth); Context.Response.Write("成功");
