答案:
采用勤哲Excel服务器不需要进行额外的编程,因为它提供了丰富的功能和API接口,可以方便地实现Excel文件的读写、计算、数据分析等操作,同时也可以通过API接口实现与其他系统的数据集成。
具体实现方式可以参考以下示例代码:
- 实现Excel文件的读取:
Dim qzExcel As New QZExcel.Excel
qzExcel.Open("D:\test.xlsx")
Dim sheet As QZExcel.Worksheet = qzExcel.ActiveSheet
Dim cell As QZExcel.Range = sheet.Cells(1,1)
Console.WriteLine(cell.Value)
qzExcel.Close()
- 实现Excel文件的写入:
Dim qzExcel As New QZExcel.Excel
qzExcel.Open("D:\test.xlsx")
Dim sheet As QZExcel.Worksheet = qzExcel.ActiveSheet
Dim cell As QZExcel.Range = sheet.Cells(1,1)
cell.Value = "Hello world!"
qzExcel.Save()
qzExcel.Close()
- 实现Excel文件的计算:
Dim qzExcel As New QZExcel.Excel
qzExcel.Open("D:\test.xlsx")
Dim sheet As QZExcel.Worksheet = qzExcel.ActiveSheet
Dim cell1 As QZExcel.Range = sheet.Cells(1,2)
cell1.Value = 1
Dim cell2 As QZExcel.Range = sheet.Cells(2,2)
cell2.Value = 2
Dim cell3 As QZExcel.Range = sheet.Cells(3,2)
cell3.Formula = "=SUM(B1:B2)"
Console.WriteLine(cell3.Value)
qzExcel.Close()
通过以上代码示例,可以看出使用勤哲Excel服务器的API接口,可以轻松实现Excel文件的读取、写入、计算等常用操作。
