使var处于for循环中

Question

这很难解释,但我会在我的代码中展示我想要的一个例子:目前我这样做:

var something1 = new (Microsoft.Office.Interop.Excel.Worksheet)appExcel.Worksheets.Add(Type.Missing, appExcel.Worksheets[appExcel.Worksheets.Count], 1, XlSheetType.xlWorksheet);
var something2 = new (Microsoft.Office.Interop.Excel.Worksheet)appExcel.Worksheets.Add(Type.Missing, appExcel.Worksheets[appExcel.Worksheets.Count], 1, XlSheetType.xlWorksheet);
var something3 = new (Microsoft.Office.Interop.Excel.Worksheet)appExcel.Worksheets.Add(Type.Missing, appExcel.Worksheets[appExcel.Worksheets.Count], 1, XlSheetType.xlWorksheet);

something1.Name = "sheet1";
something2.Name = "sheet2";
something3.Name = "sheet3";

我想在for循环中制作那些var这是我认为它应该是:

for (int i=1;i<4;i++)
{
   var ("something" +i) = new Microsoft.Office.Interop.Excel.Worksheet)appExcel.Worksheets.Add(Type.Missing, appExcel.Worksheets[appExcel.Worksheets.Count], 1, XlSheetType.xlWorksheet); // this (of course) doenst work
}

关于如何做到这一点的任何想法？

我试过这个,但它不起作用:

var something = new (Microsoft.Office.Interop.Excel.Worksheet)appExcel.Worksheets.Add(Type.Missing, appExcel.Worksheets[appExcel.Worksheets.Count], 1 , XlSheetType.xlWorksheet)[4];

你可以使用字典

var somethigs = new Dictionary<int, xxx.ApplicationClass>();
for (var i = 1; i < 4; i++)
{
    somethigs[i] = new xxx.ApplicationClass();
}

//access them like this

somethigs[1].Name = "sheet1";
somethigs[2].Name = "sheet2";

或使用这样的数组

var somethigs = new xxx.ApplicationClass[4];
for (var i = 0; i < 4; i++)
{
    somethigs[i] = new xxx.ApplicationClass();
}

somethigs[0].Name = "sheet1";
somethigs[1].Name = "sheet2";

请记住,数组具有零基索引.
