阅读Excel表格使用C＃合并单元格来创build一个XML

我有一个excel的格式：

col1 col2 col3 col4 col5 Row 1: 1 Head data1 r11 r12 Row 2: 1 Head data2 r21 r22 Row 3: 1 Head data3 r31 r32 Row 4: 1 Head data4 r41 r42 Row 5: 1 Head data5 r51 r52 Row 6: 1 Head2 data6 r61 r62 Row 7: 1 Head2 data7 r71 r72 Row 8: 1 Head2 data7 r81 r82 Row 9: 1 Head2 data8 r91 r92 Row 10: 1 Head2 data9 r101 r102 Row 11: 1 Head2 data10 r111 r112 Row 12: 1 Head2 data11 r121 r122 Row 13: 1 Head2 data12 r131 r132 Row 14: 1 Head2 data13 r141 r142 

上面的excel是这样的，连续的相同的值意味着它们被合并 。

合并的单元格是

  " Row1col1 to Row14col1" with value :"1" " Row1col2 to Row5col2" with value : "Head" "Row6Col2 to Row14col2" with value : "Head2" 

读取一个没有任何合并单元格的Excel可以通过这样的OLEDB来完成;

  OleDbCommand command = new OleDbCommand("Select * FROM [Sheet1$] ", connection); connection.Open(); XmlDocument doc = new XmlDocument(); 

但是如何读取合并的单元格并将其格式化为像这样的xml;

具有子节点data1到data6的节点Head和每个子节点具有col4和col5的级联。

例如：

 <node name="Head"> <subnode name="data1" sum="r11+r12"></subnode> <subnode name="data2" sum="r21+r22"></subnode> 

等等….

EDIT2

根据@lloydm输出是这样的：

  <node> <subnode name="Head" sum="data1r11" /> <subnode name="" sum="data2r21" /> <subnode name="" sum="data3r31" /> <subnode name="" sum="data4r41" /> <subnode name="" sum="data5r51" /> <subnode name="Head2" sum="data6r61" /> <subnode name="" sum="data7r71" /> <subnode name="" sum="data8r81" /> <subnode name="" sum="data9r91" /> </node> 

那么，我该如何得到一个输出：

 <node> <subnode name="Head" /> <subsubnode name="data2" sum="data2r21" /> <subsubnode name="data3" sum="data3r31" /> <subsubnode name="data4" sum="data4r41" /> etc... </subnode> <subnode name="Head2" /> <subsubnode name="data2" sum="data2r21" /> <subsubnode name="data3" sum="data3r31" /> <subsubnode name="data4" sum="data4r41" /> etc... </subnode> </node> 

Answer 1

用数据读取器添加一个属性

 using System; using System.Data.OleDb; using System.Xml; using System.Data.Common; public class Program { public static void Main() { string connectionString =""; XmlDocument doc = new XmlDocument(); using (OleDbConnection connection = new OleDbConnection(connectionString)) { connection.Open(); OleDbCommand command = new OleDbCommand("Select * FROM [Sheet1$] ", connection); XmlElement root = doc.CreateElement("node"); doc.AppendChild(root); using (DbDataReader dr = command.ExecuteReader()) { while (dr.Read()) { #region Field Matrices // Field Matrix string r01 = dr.GetValue(0).ToString(); string r11 = dr.GetValue(1).ToString(); string r21 = dr.GetValue(2).ToString(); XmlElement subnode = doc.CreateElement("subnode"); root.AppendChild(subnode); XmlAttribute name = doc.CreateAttribute("name"); name.Value = r01; subnode.Attributes.Append(name); XmlAttribute sum = doc.CreateAttribute("sum"); sum.Value = r11 + r21; subnode.Attributes.Append(sum); } } } doc.Save(Console.Out); } 

}
