安装步骤:
1、在Embarcadero RAD Studio XE2主菜单中依次点击"Component->Install Packages"添加(Add)XLSRWII5_DXE版本号.bpl
2、在Embarcadero RAD Studio XE4主菜单中依次点击“Toosl->Options->Delphi Options->Library->Library Path”分别添加Library Path:Obj和XLSReadWriteII的完整路径

在Delphi中读取Excel文件,使用CreateOleObject的方式挺讨厌的,一直搞不定,输出了文件之后,总会在系统中打开一个Excel,就算Quit也不行,一个程序中使用的多了,还不定搞出什么事情来。狠狠心找个其它的东西来代替,于是发现了XlsReadWriteII。

使用之后发现这个东西真不错,简单好用。不管是读还是写均轻松搞定。下面是官方的Demo中的代码。

写文件代码,包括对格式的定制:

[delphi] view plaincopyprint?在CODE上查看代码片派生到我的代码片
XLS.Filename := 'FormatSample.xls';
XLS.Clear;
// Add format #0
with XLS.Formats.Add do begin
FontIndex := XLS.Fonts.AddIndex;
XLS.Fonts[FontIndex].Name := 'Courier new';
XLS.Fonts[FontIndex].Size := 14;
XLS.Fonts[FontIndex].Color := xcRed;
end;
// Add format #1
with XLS.Formats.Add do begin
FontIndex := XLS.Fonts.AddIndex;
XLS.Fonts[FontIndex].AssignTFont(Font);
end;
// Add format #2
with XLS.Formats.Add do begin
FillPatternForeColor := xcLilac;
end;
// Add format #3
with XLS.Formats.Add do begin
BorderTopColor := xcBlue;
BorderBottomColor := xcBlue;
BorderTopStyle := cbsThin;
BorderBottomStyle := cbsThick;
end;
// Add format #4
// ShortDateFormat is a Delphi global variable for the local date format.
with XLS.Formats.Add do begin
NumberFormat := ShortDateFormat;
end;
XLS.Sheets[0].WriteString(1,2,0,'Format #0');
XLS.Sheets[0].WriteString(1,3,1,'Format #1');
XLS.Sheets[0].WriteString(1,4,2,'Format #2');
XLS.Sheets[0].WriteString(1,5,3,'Format #3');
XLS.Sheets[0].WriteNumber(1,6,4,Date);
XLS.Write; //如果需要另存为一个文件,改FileName之后再写一次,如需更改工作簿的名称,设置Sheets[0].Name就可以了。

读取文件代码:

[delphi] view plaincopyprint?在CODE上查看代码片派生到我的代码片
var
Col,Row: integer;
Sum: double;
begin
if edFilename.Text = '' then begin
ShowMessage('Filename is missing');
Exit;
end;
Sum := 0;
XLS.Filename := edFilename.Text;
XLS.Read; //此行不能省,否则读取不到数据
XLS.Sheets[0].LastCol := 255;
XLS.Sheets[0].LastRow := 65535;
for Col := XLS.Sheets[0].FirstCol to XLS.Sheets[0].LastCol do begin
for Row := XLS.Sheets[0].FirstRow to XLS.Sheets[0].LastRow do begin
if (Row < Grid.RowCount) and (Col < Grid.ColCount) then
Grid.Cells[Col + 1,Row + 1] := XLS.Sheets[0].AsFmtString[Col,Row];
if XLS.Sheets[0].CellType[Col,Row] = ctFloat then
Sum := Sum + XLS.Sheets[0].AsFloat[Col,Row];
end;
end;
lblSum.Caption := Format('The sum of all numeric cells are: %.2f',[Sum]);
Grid.Invalidate;
end;

温馨提示:

XE5报错解决方案:

1、[dcc32 Error] Unit1.pas(51): E2003 Undeclared identifier: 'ctFloat'

[delphi] view plaincopyprint?在CODE上查看代码片派生到我的代码片
uses XLSSheetData5, XLSReadWriteII5, Xc12Utils5;//增加引用:Xc12Utils5
ctFloat修改为xctFloat


2、[dcc32 Error] Unit1.pas(42): E2064 Left side cannot be assigned to

[delphi] view plaincopyprint?在CODE上查看代码片派生到我的代码片
XLS.Sheets[0].LastCol := 255;
XLS.Sheets[0].LastRow := 65535;
删除或者注释掉即可

3、别名说明:

XLS是XLSReadWriteII5组件的Name,Grid是StringGrid组件的Name
