从Excel文件读取数据

Question

我在使用C＃编写Excel电子表格时遇到了一些麻烦。 我有这样的代码，我读出每一个细胞，从A到X.

System.Array myvalues; string[] strArray; 
Microsoft.Office.Interop.Excel.Range range = 
    worksheet.get_Range("A" + i.ToString(), "W" + i.ToString()); 

while(range.Count!=0) 
{ 
    i++; 
    //Console.WriteLine(i); 
    range = worksheet.get_Range("A" + i.ToString(), "W" + i.ToString()); 
    myvalues = (System.Array)range.Cells.Value; 
    strArray = ConvertToStringArray(myvalues); 
    name = clearstr(strArray[1]); 

    for (int j = 1 ; j <= Int32.Parse(number_add_file)*4 ; j++) 
    { 
     name = ""; 
     lang_add = ""; 
     price = ""; 
     description = ""; 
     Console.WriteLine("I got in!"); 

     Microsoft.Office.Interop.Excel.Range range_add = 
      worksheet.get_Range("X" + i.ToString(),Type.Missing); 

     System.Array values = (System.Array)range_add.Cells.Value; 
     string[] str = ConvertToStringArray(values); 
     name = str[0]; 
     lang_add = str[1]; 
     price = str[2]; 
     description = str[3]; 
     Console.WriteLine(name + " " 
      + lang_add + " " + price + " " + description); 

     addfile(); 
    } 

我的问题是：我怎么能以“数量”值，下一个读取Excel中的4 *“号”行？

例如：

  A B C D E F G H I J 
     a a a a a 1 a a a a 

F公司细胞值是1，所以我想读（GHIJ） 若F的单元格的值是2的我想读取（GHIJKLMN）

  A B C D E F G H I J K L M N 
     a a a a a 2 a a a a a a a a 

F公司单元格值3：

 A B C D E F G H I J K L M N O P Q R 
     a a a a a 3 a a a a a a a a a a a a

这是.NET 4.0：

using Excel = Microsoft.Office.Interop.Excel; 
Excel.Application xlApp = new Excel.Application(); 
Excel.Workbook xlWorkbook = xlApp.Workbooks.Open("somefile.xls"); 
Excel.Worksheet xlWorksheet = xlWorkbook.Sheets[1]; // assume it is the first sheet 
Excel.Range xlRange = xlWorksheet.UsedRange; // get the entire used range 
int value = 0; 
if(Int32.TryParse(xlRange.Cells[1,6].Value2.ToString(), out value)) // get the F cell from the first row 
{ 
    int numberOfColumnsToRead = value * 4; 
    for(int col=7; col < (numberOfColumnsToRead + 7); col++) 
    { 
     Console.WriteLine(xlRange.Cells[1,col].Value2.ToString()); // do whatever with value 
    } 
} 

这将打开工作簿，并得到工作簿中的第一个工作表。然后我们得到整个使用的范围并将其放入范围变量中。从那里，我们尝试在第一行中解析列“F”中的整数（这是第6列，它基于1而不是从零开始）。如果解析成功，我们再将这个数字乘以4，看看你需要多少列（在你的文章中你说过行，但你的例子是列）。我们使用for循环在G列（第7列）处开始并转到列数以读取+7（以说明我们跳过的列）。你可以自由地做你想要的值，但对于这个例子，我只是写了他们到控制台。

这是inot直接回答你的问题，但ÿ OU可以轻松地参考您的细胞是这样的：

int row1 = 1; 
int row2 = 5; 

sheet1.Cells[row1, row1+row2].Value=row1.ToString(); 
String Rng = Convert.ToString(sheet1.Cells[row1, row2-row1].Address());
