        string myExcelDataQuery = "Select * from [TestReport$],sExcelConnectionString";
        OleDbConnection OleDbConn = new OleDbConnection(sExcelConnectionString);

Take a look at,

string cnstr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\\sample.xls;Extended Properties=" + "\"Excel 8.0;HDR=YES\"";
            using (System.Data.OleDb.OleDbDataAdapter adp=new System.Data.OleDb.OleDbDataAdapter("select * from [TestReport$]",cnstr))
                DataTable dt = new DataTable();
                listBox1.DataSource = dt;
                listBox1.DisplayMember = dt.Columns[0].ColumnName;
                listBox1.ValueMember  = dt.Columns[1].ColumnName;

Thanks for the response.

I am getting error at " adp.Fill(dt);"
Error :
'TestReport$' is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long.

Please help me with this.
