Question

With c# and LinqToSql I query a database Table and return a single unique record.

QUESTION:
How do I place the results of my query into a Dictionary with:
the Column Names of the database Table as the Dictionary Keys and
the Column Values of the database Table as the Dictionary Values.

Note: I will not always know the name or number of the Table’s Column Names

Dictionary<string, string> QueryResult = new Dictionary<string, string>

var UniqueRecord = (from tbl DataContext.Table
                                 where tbl.ColumnName1.Equals(Parameter1) 
                                 && tbl.ColumnName2.Equals(Parameter2)
                                 select tbl);

//How do I add var UniqueRecord to the Dictionary

==================================================================================

I eventually used this

==================================================================================

var UniqueRecord = (from tbl DataContext.Table
                                 where tbl.ColumnName1.Equals(Parameter1) 
                                 && tbl.ColumnName2.Equals(Parameter2)
                                 select tbl);


 foreach(var item in OnlineBezeichnungRekord)
 {
   var properties = item.GetType()
                        .GetProperties()
                        .ToDictionary(p => p.Name, p => p.GetValue(item, null).ToString());

   Dictionary<string,string> DictionaryValues = properties;

  }

Answer 1

Considering how simple it is to convert a DataRow into a Dictionary manually, I would not go with Enumerable.ToDictionary in your case, and just do loops:

Private Function GetDictionaryFromDataRow(dr As DataRow) As Dictionary(Of String, Object)
  Dim dict As New Dictionary(Of String, Object)
  For Each col As DataColumn In dr.Table.Columns
    dict.Add(col.ColumnName, dr.Item(col))
  Next
  Return dict
End Function

Then just make sure your query returns a DataRow, so use UniqueRecord(0).
