net输出文本文件

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");
