我已经在 .NET 上尝试过这段代码 - 将 excel 文件导入 devxpress datagrid - 它工作正常，但我现在必须创建一个在 delphi 上执行相同工作的程序。我对delphi不太了解，所以我需要一些想法如何做到这一点。
public static DataTable ImportExcelXLS(string FileName, bool hasHeaders)
{
string HDR = hasHeaders ? "Yes" : "No";
string strConn;
if (FileName.Substring(FileName.LastIndexOf('.')).ToLower() == ".xlsx")
strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + FileName + ";Extended Properties=\"Excel 12.0;HDR=" + HDR + ";IMEX=0\"";
else
strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + FileName + ";Extended Properties=\"Excel 8.0;HDR=" + HDR + ";IMEX=0\"";
//DataSet output = new DataSet();
using (OleDbConnection conn = new OleDbConnection(strConn))
{
conn.Open();
DataTable schemaTable = conn.GetOleDbSchemaTable(
OleDbSchemaGuid.Tables, new object[] { null, null, null, "TABLE" });
foreach (DataRow schemaRow in schemaTable.Rows)
{
string sheet = schemaRow["TABLE_NAME"].ToString();
if (!sheet.EndsWith("_"))
{
try
{
OleDbCommand cmd = new OleDbCommand("SELECT * FROM [" + sheet + "]", conn);
cmd.CommandType = CommandType.Text;
DataTable outputTable = new DataTable(sheet);
new OleDbDataAdapter(cmd).Fill(outputTable);
if (outputTable.Rows.Count > 0)
{
return outputTable;
}
}
catch (Exception ex)
{
throw new Exception(ex.Message + string.Format("Sheet:{0}.File:F{1}", sheet, FileName), ex);
}
}
}
}
return null;
}
