在C#中,如何从Excel文件中的工作表中获取列名?
到目前为止,这是我的代码:
ConnectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=\"Excel 12.0 Xml;HDR=YES;IMEX=1\";", "@"C:\file.xlsx");
objConn.Open();
OleDbCommand objCmdSelect = new OleDbCommand("SELECT * FROM ["xlWorksheet"$]", objConn);
OleDbDataAdapter objAdapter1 = new OleDbDataAdapter();
objAdapter1.SelectCommand = objCmdSelect;
DataSet objDataset1 = new DataSet();
objAdapter1.Fill(objDataset1);
objConn.Close();
答案 0 :(得分:4)
您的连接字符串是否包含 HDR = YES ?:
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\myFolder\myExcel2007file.xlsx;Extended Properties="Excel 12.0 Xml;HDR=YES";
填充DataTable或DataSet后,您可以按常规方式处理:
dt.Columns[0].ColumnName
或者:
// For each DataTable, print the ColumnName.
foreach(DataTable table in dataSet.Tables)
{
foreach(DataColumn column in table.Columns)
{
Console.WriteLine(column.ColumnName);
}
}
此外,这看起来不正确:
OleDbCommand objCmdSelect = new OleDbCommand("SELECT * FROM ["xlWorksheet"$]", objConn);
应该是这样的:
OleDbCommand objCmdSelect = new OleDbCommand("SELECT * FROM [" + xlWorksheet + "$]", objConn);
