将excel工作表提取到C＃中的字符串中＃

Question

如何将excel工作表提取到使用C＃的字符串中？ 我已经有工作表，可以保存为txt文件，但不是那个 我想直接将它解压缩为字符串并进行一些处理。

Answer 1

这样（未经测试）代码的东西应该工作：

Excel.Application oXL= new Excel.Application(); 
oXL.Visible = true; 
Excel._Workbook oWB = (Excel._Workbook)(oXL.Workbooks.Add(Missing.Value)); 
Excel._Worksheet oSheet = (Excel._Worksheet)oWB.ActiveSheet; 
string s = (string)oSheet.Cells[1, 1].Value; 

虽然看这个sample，看看如何清理一切正常等

尝试使用辉煌EPPlus库允许您加载电子表格并以编程方式访问所有单元格。

下面是几个例子：

//Select all cells in column d between 9990 and 10000 
var query1= (from cell in sheet.Cells["d:d"] where cell.Value is double && (double)cell.Value >= 9990 && (double)cell.Value <= 10000 select cell); 
//In combination with the Range.Offset method you can also check values of other columns... 


//Here we use more than one column in the where clause. 
//We start by searching column D, then use the Offset method to check the value of column C. 
var query3 = (from cell in sheet.Cells["d:d"] 
        where cell.Value is double && 
           (double)cell.Value >= 9500 && (double)cell.Value <= 10000 && 
           cell.Offset(0, -1).Value is double &&  //Column C is a double since its not a default date format. 
           DateTime.FromOADate((double)cell.Offset(0, -1).Value).Year == DateTime.Today.Year+1 
        select cell); 

Console.WriteLine(); 
Console.WriteLine("Print all cells with a value between 9500 and 10000 in column D and the year of Column C is {0} ...", DateTime.Today.Year + 1); 
Console.WriteLine();  

count = 0; 
//The cells returned here will all be in column D, since that is the address in the indexer. 
//Use the Offset method to print any other cells from the same row. 
foreach (var cell in query3)  
{ 
    Console.WriteLine("Cell {0} has value {1:N0} Date is {2:d}", cell.Address, cell.Value, DateTime.FromOADate((double)cell.Offset(0, -1).Value)); 
    count++; 
}
