与灵感之源的vb.net对应的SmartExcel的C#版本

我的代码，是从sf.net上down下来的vb.net的版本。该版本已经很久没有进行维护了。我将其转化到了C#版本。不过说实话，没有一个WYSWYG的ide（如excel的designer），这段代码没什么作用。写一个excel文件，太复杂了。。。

下面是SmartExcel.CS的代码，其他的代码，我都放在回复里面，请慢慢看。。。

using System;
using System.IO;
using System.Runtime.InteropServices;
using System.Reflection;

namespace Genersoft.Platform.Application.SmartExcel
}

excel确实很小，对了，我忘记把C#的test代码放上来了，生成的excel才554字节。

下面是根据灵感老大的demo我用C#翻的代码，请看：

private void button1_Click(object sender, System.EventArgs e)
{
SmartExcel excel = new SmartExcel();
excel.CreateFile("c:\\test.xls");
excel.PrintGridLines = false;

double height = 1.5;

excel.SetMargin(MarginTypes.TopMargin, height);
excel.SetMargin(MarginTypes.BottomMargin, height);
excel.SetMargin(MarginTypes.LeftMargin, height);
excel.SetMargin(MarginTypes.RightMargin, height);

string font = "Arial";
short fontsize = 12;
excel.SetFont(font,fontsize,FontFormatting.Italic);

byte b1 = 1,b2 = 12;
short s3 = 18;
excel.SetColumnWidth(b1,b2,s3);

string header = "头";
string footer = "角";
excel.SetHeader(header);
excel .SetFooter(footer);

int row = 1,col = 1,cellformat = 0;
object title = "没有使用任何EXCEL组件，直接写成了一个EXCEL文件，cool吧？！";
excel.WriteValue(ValueTypes.Text,CellFont.Font0,CellAlignment.LeftAlign,CellHiddenLocked.Normal,row,col,title,cellformat);

excel.CloseFile();
}

对了，代码中原来的ref参数的处理，都被我去掉了。
