Thank you very much for your solution. For future reference, I've modified your code to ensure object disposal:

System.Data.DataTable dtExcel = new System.Data.DataTable();
dtExcel.TableName = "MyExcelData";
string SourceConstr = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source='MyExcelFilePath';Extended Properties= 'Excel 8.0;HDR=Yes;IMEX=1'";
using (OleDbConnection con = new OleDbConnection(SourceConstr))
using (OleDbDataAdapter data = new OleDbDataAdapter("Select * from [Sheet1$]", con))
{
data.Fill(dtExcel);
}

Hello Pravesh Singh,

Check this code...

System.Data.DataTable
dtExcel = new System.Data.DataTable();
dtExcel.TableName = "MyExcelData";
string SourceConstr = @"Provider=Microsoft.ACE.OLEDB.12.0;Data
Source='MyExcelFilePath';Extended Properties= 'Excel 8.0;HDR=Yes;IMEX=1'";
OleDbConnection con = new OleDbConnection(SourceConstr);
string query = "Select
* from [Sheet1$]";
OleDbDataAdapter data = new OleDbDataAdapter(query,
con);
data.Fill(dtExcel);

It might be resolve your problem.
