Question

我创建了一个从Excel文件中读取的控制台应用程序。我想获取所有文档编号并将其放在一个数组中以便进行搜索。我能够找到包含数据“DocumentNumber”的单元格，例如$ F $ 5。如何遍历F列中的行？我有以下代码：

public static void Main(string[] args)
    {
        string address;
        string next;
        try
        {
            Excel.ApplicationClass excel = new Excel.ApplicationClass();
            Excel.Workbook workbook = excel.Workbooks.Open(@"D:\sample.xls", Missing.Value, Missing.Value,
                Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value,
                Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value,
                Missing.Value, Missing.Value);
            Excel.Worksheet worksheet = (Excel.Worksheet)workbook.Sheets["Sheet1"];
            Excel.Range docNumber = worksheet.Cells.Find("DocumentNumber", worksheet.Cells[1, 1], Excel.XlFindLookIn.xlValues,
                Excel.XlLookAt.xlPart, Missing.Value, Excel.XlSearchDirection.xlNext,
                false, Missing.Value, Missing.Value);

            if(docNumber != null){
                address = docNumber.get_Address(true, true, Excel.XlReferenceStyle.xlA1, Missing.Value, Missing.Value);
                Console.WriteLine(address);

            }
        }
        catch (Exception err)
        {
            Console.WriteLine(err.Message);
        }
    }

提前致谢。

请仔细研究。它遍历每一行和每一行。

string address;  
string next; 

try {  
    Excel.ApplicationClass excel = new Excel.ApplicationClass();
    object Missing = Type.Missing;
    FileInfo fInfo = new FileInfo(@"D:\sample.xls");

    if(fInfo.Exists) {
        Excel.Workbook workbook = excel.Workbooks.Open(@"D:\sample.xls", Missing, Missing, 
                    Missing, Missing, Missing, Missing, Missing,  
                    Missing, Missing, Missing, Missing, Missing,  
                    Missing, Missing);      
        Excel.Worksheet worksheet = (Excel.Worksheet)workbook.Sheets["Sheet1"];
        Excel.Range docNumber = worksheet.Cells.Find("DDEC", worksheet.Cells[1, 1], 
        Excel.XlFindLookIn.xlValues, Excel.XlLookAt.xlPart, Missing, Excel.XlSearchDirection.xlNext, false, Missing, Missing);     

        if(docNumber != null) {
            address = docNumber.get_Address(true, true, Excel.XlReferenceStyle.xlA1, Missing, Missing);
            docNumber = worksheet.UsedRange;                        

            for (int rCnt = 1; rCnt <= docNumber.Rows.Count; rCnt++) {
                for (int cCnt = 1; cCnt <= docNumber.Columns.Count; cCnt++) {
                    string str = (string)(docNumber.Cells[rCnt, cCnt] as Excel.Range).Value2;
                    MessageBox.Show(str);
                }
            }
            Console.WriteLine(address); 
        }     
    }
}

使用OLEDB读取数据会不会更容易？更清晰的语法，然后您可以预先返回返回的DataTable。
