首先的一步就是使用Tlbimp這個(gè)工具將Excel9.0的對(duì)象庫(kù)文件Excel8.olb轉(zhuǎn)換成為dll，這樣才能做為.Net平臺(tái)Assembly來(lái)使用：）操作如下：

TlbImp Excel9.olb Excel.dll

只要有了這個(gè)Excel.dll，現(xiàn)在我們就能使用Excel的各種操作函數(shù)了。
下面就讓我們具體看看C#是如何使用這些東東吧。

1. 創(chuàng)建一個(gè)新Excel的Application:

Application exc = new Application();
if (exc == null) {
Console.WriteLine("ERROR: EXCEL couldn"t be started");
return 0;
}

2. 讓這個(gè)工程可見(jiàn):

exc.set_Visible(0, true);

3. 獲取WorkBooks集合:

Workbooks workbooks = exc.Workbooks;

4. 加入新的WorkBook:

_Workbook workbook = workbooks.Add(XlWBATemplate.xlWBATWorksheet, 0);

5. 獲取WorkSheets集合:

_Worksheet worksheet = (_Worksheet) sheets.get_Item(1);
if (worksheet == null) {
Console.WriteLine ("ERROR in worksheet == null");
}

6. 給單元格設(shè)置變量：

Range range1 = worksheet.get_Range("C1", Missing.Value);
if (range1 == null) {
Console.WriteLine ("ERROR: range == null");
}
const int nCells = 1;
Object[] args1 = new Object[1];
args1[0] = nCells;
range1.GetType().InvokeMember("Value", BindingFlags.SetProperty, null, range1, args1);

例程:

using System;
using System.Reflection;
using System.Runtime.InteropServices;
using Excel;

class Excel {
public static int Main() {
Application exc = new Application();
if (exc == null) {
Console.WriteLine("ERROR: EXCEL couldn"t be started!");
return 0;
}

exc.set_Visible(0, true);
Workbooks workbooks = exc.Workbooks;
_Workbook workbook = workbooks.Add(XlWBATemplate.xlWBATWorksheet, 0);
Sheets sheets = workbook.Worksheets;

_Worksheet worksheet = (_Worksheet) sheets.get_Item(1);
if (worksheet == null) {
Console.WriteLine ("ERROR: worksheet == null");
}

Range range1 = worksheet.get_Range("C1", Missing.Value);
if (range1 == null) {
Console.WriteLine ("ERROR: range == null");
}
const int nCells = 1;
Object[] args1 = new Object[1];
args1[0] = nCells;
range1.GetType().InvokeMember("Value", BindingFlags.SetProperty, null,range1, args1);
return 100;
}
}

現(xiàn)在我們來(lái)看看如何使用數(shù)組，他有些類似于設(shè)置單元格。僅僅需要的改變只是args2[0] = array2;
const int nCell = 5;
Range range2 = worksheet.get_Range("A1", "E1");
int[] array2 = new int [nCell];
for (int i=0; i < array2.GetLength(0); i++) {
array2[i] = i+1;
}
Object[] args2 = new Object[1];
args2[0] = array2;
range2.GetType().InvokeMember("Value", BindingFlags.SetProperty, null, range2, args2);

　　大家需要了解Tlbimp這個(gè)工具的使用啊：）這個(gè)東東很有用，可以將普通Win32程序移植到.Net下面來(lái)：）
