如何读取Excel生成的XML文件？

[极速小王子]

如题！！
要求是读出文件中的每个表以及表中的内容，读到一个逻辑空间为“表”的数据结构中
不知道MS提供现成的类没有！
望指点！

没有，你只能用Excel.Application对象来读出excel的内容，然后自己写入表中

[jizhe]

string connectionString = "Driver={Microsoft Excel Driver (*.xls)};DBQ=" + filename;

ODBCAccess odbc = new ODBCAccess(connectionString);
string sql = "select * from [" + 每个表+ "$]";

运行sql取得DataSet
再用下面函数写入文件

private void WriteXmlToFile(DataSet thisDataSet) {
if (thisDataSet == null) { return; }
// Create a file name to write to.
string filename = "myXmlDoc.xml";
// Create the FileStream to write with.
System.IO.FileStream myFileStream = new System.IO.FileStream
(filename, System.IO.FileMode.Create);
// Create an XmlTextWriter with the fileStream.
System.Xml.XmlTextWriter myXmlWriter =
new System.Xml.XmlTextWriter(myFileStream, System.Text.Encoding.Unicode);
// Write to the file with the WriteXml method.
thisDataSet.WriteXml(myXmlWriter);
myXmlWriter.Close();
}

从excel里导入到dataset里，然后dataset.writexml

注意，我的问题是不通过SQL，而是直接通过文件操作或MS提供的类来读取，有现成的么？

string sql1=@"Driver=Microsoft Excel Driver (*.xls);DBQ=d:\temp\"+this.Session["username"].ToString()+".xls";
string sql2="SELECT distinct * FROM [Sheet1$] ";
OdbcConnection myConnection = new OdbcConnection(sql);
OdbcDataAdapter myCommand=null;
try
{
myCommand = new OdbcDataAdapter(sql2, myConnection);
}
catch
{
this.Label5.Text="打开excel表失败";
return;
}
DataSet ds = new DataSet();
myCommand.Fill(ds, "newtable");
ds.writexml
