I want read file Exel file, I done:

static DataTable GetSheetData(string excelFile, int sheetindex){  
string sheetname = GetExcelSheetNames(excelFile)[sheetindex];  
string srcConnString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + excelFile + @";Extended Properties=""Excel 8.0;HDR=YES;""";  
string srcQuery = "Select * from [" + sheetname + "]";  
OleDbConnection srcConn = new OleDbConnection(srcConnString);  
srcConn.Open();  
OleDbCommand objCmdSelect = new OleDbCommand(srcQuery, srcConn);  
DataSet ds = new DataSet();  
OleDbDataAdapter da = new OleDbDataAdapter(objCmdSelect);  
da.Fill(ds, sheetname);  
srcConn.Close();  
return ds.Tables[0];  
}  

If sheetname have blank charaters blanks, I can't read file. How can read the file when sheetname blank characters? Thanks
