QuestionBoolean function to return true/false Pin

I have the following function which I got online, and have changed to suit my needs :-

private Boolean SheetExists(string strFilename)
{
    Boolean Match = false;
    OleDbConnection objConn = null;
    System.Data.DataTable dt = null;
    try
    {
        String connString = "Provider=Microsoft.Jet.OLEDB.4.0;" +
            "Data Source=" + strFilename + ";Extended Properties=Excel 8.0;";
        objConn = new OleDbConnection(connString);
        objConn.Open();
        dt = objConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
        String[] excelSheets = new String[dt.Rows.Count];
        int i = 0;
        foreach (DataRow row in dt.Rows)
        {
            excelSheets[i] = row["TABLE_NAME"].ToString();
            i++;
        }
        for (int j = 0; j < excelSheets.Length; j++)
        {
            if (excelSheets[j] == "Sheet1$")
            {
                Match = true;
            }
        }
        if (Match == true)
            return true;
        else
            return false;
    }
    finally
    {
        if (objConn != null)
        {
            objConn.Close();
            objConn.Dispose();
        }
        if (dt != null)
        {
            dt.Dispose();
        }
    }
}


Basically it checks if sheet1 exists in a workbook. I'm currently using the variable "Match" to obtain a "return true" or a "return false". I'm sure it possible to modify the code so that it returns the true/false directly, I just can't figure out how.
Any ideas? Thanks
