您的 excelSheets 变量是一个字符串数组，请尝试以下操作：

foreach(String str in excelSheets)
{
    messagebox.show(str);
}

为什么使用 OLE？您可以使用 VSTO 并命名您的 excelsheet，如下例所示：

var excelApp = new Microsoft.Office.Interop.Excel.Application();
excelApp.Visible = true;
var excelWorkbook = excelApp.Workbooks.Add();
Worksheet excelSheet = excelWorkbook.Sheets.Add();
excelSheet.Name = "My sheetname";
