I want to check if a particular row exists in Data table or not. 

E.g., I want to check if Property Table Exists in msi data table or not. If it exists then I want to check if "Property" column and "Value" column exists or not. If both exists then I want to check if Property "ARPNOMODIFY" exists or not. 

```
                if (database.Tables.Contains("Property"))
                {
                    if (database.Tables["Property"].Columns.Contains("Property"))
                    {
                        // here I want to checked if "ARPNOMODIFY" or any other property exists or not. If it exists then I want its value.
                    }
                }

```

I have one data table having structure as( "TableName","ColumnNAme1","ColumnName2","Value at ColumnName1"). So for above record the row is like ("Property","Property","Value","ARPNOMODIFY") and I want to return Value 1 as ARPNOMODIFY exists and its value is 1. 

Now consider another row as ("Property","Propery","Value","ICFAGREE"). Now if ICFAGREE property doesn't exists in Property table then I want to return null string.
Thanks in advance.

Also Consider another row ("AdminExecuteSequence","Action","Condition","SetSpecifiedDir"). Now in this example AdminExecuteSequence table has Action and Condition columns. One of value under Action columns is "SetSpecifiedDir" so its corresponding value under "Condition" column is "ORCADIR".So I want to return "ORCADIR" this string, If "SetSpecifiedDir" value exists in AdminExecuteSequence table or else I would return null.
