我想合并单元格并多次执行...我使用此合并的原因是因为我想要更多的一张表。每个表的列数不同，另一个表的列的大小不同......合并的数量和位置未知
using Microsoft.Office.Interop.Excel;
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApp111
{
class Program
{
static void Main(string[] args)
{
string x = @"C:\Users\hed-b\source\repos\TESTUserFormFromExcel\ConsoleApp111\bin\Debug\TEST.xltm";
Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application
{
DisplayAlerts = false,
Visible = false,
ScreenUpdating = false,
};
Workbook wb = xlApp.Workbooks.Open(x);
Worksheet ws = (Worksheet)wb.Worksheets[1];
if (ws == null)
{
Console.WriteLine("Worksheet could not be created. Check that your office installation and project references are correct.");
return;
}
Stopwatch stopWatch = Stopwatch.StartNew();
for (int i = 2; i <= 10; i++)
{
ws.get_Range("A"+i, "B"+i).Merge();
}
for (int i = 2; i <= 10; i++)
{
ws.get_Range("C" + i, "D" + i).Merge();
}
for (int i = 2; i <= 10; i++)
{
ws.get_Range("E" + i, "H" + i).Merge();
}
Console.WriteLine(stopWatch.ElapsedMilliseconds);
stopWatch = Stopwatch.StartNew();
ws.get_Range("A" + 2, "H" + 10).Value2 = new string[10, 5]{
{ "aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"},
{ "aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"},
{ "aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"},
{ "aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"},
{ "aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"},
{ "aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"},
{ "aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"},
{ "aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"},
{ "aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"},
{ "aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaa","","aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"},
};
ws.get_Range("A" + 11, "H" + 15).Value2 = new string[5, 8]{
{ "bbbbb","bbbbb","bbbbb","bbbbb","bbbbb","bbbbb","bbbbb","bbbbb"},
{ "bbbbb","bbbbb","bbbbb","bbbbb","bbbbb","bbbbb","bbbbb","bbbbb"},
{ "bbbbb","bbbbb","bbbbb","bbbbb","bbbbb","bbbbb","bbbbb","bbbbb"},
{ "bbbbb","bbbbb","bbbbb","bbbbb","bbbbb","bbbbb","bbbbb","bbbbb"},
{ "bbbbb","bbbbb","bbbbb","bbbbb","bbbbb","bbbbb","bbbbb","bbbbb"}
};
Console.WriteLine(stopWatch.ElapsedMilliseconds);
xlApp.ScreenUpdating = true;
xlApp.Visible = true;
}
}
}
我只是在寻找更好的方法来更快地做到这一点
所有这些示例程序合并大约需要 1724 毫秒。在我的实际程序中，我有更多的合并并且花费了超过 5000 毫秒。这合并了它最花时间的东西......
如果您一次执行合并并让 Excel 处理您需要合并的多个范围，它的性能可能会更好。
即定义一个包含多个区域的范围对象并调用Merge它。它不会将所有内容合并到一个大的脂肪单元中，而是会按照定义合并多个区域：
var ranges = String.Empty();
for (int i = 2; i <= 10; i++)
{
ranges += $"A{i}:B{i},C{i}:D{i},E{i}:H{i},";
}
ws.get_Range(ranges.TrimEnd(',')).Merge();
