how to convert var type to datatable in c#?

IEnumerable<datarow> query = NgDb.UCB_Cimplicity_EReferral_GetFulfillmentsV2(companyID, clientID, programID, supplierName);
// Create a table from the query.
DataTable boundTable = query.CopyToDataTable<datarow>();

public DataTable LINQResultToDataTable<t>(IEnumerable<t> Linqlist)  
       {  
           DataTable dt = new DataTable();           
           PropertyInfo[] columns = null;  
           if (Linqlist == null) return dt;  
           foreach (T Record in Linqlist)  
           {                 
               if (columns == null)  
               {  
                   columns = ((Type)Record.GetType()).GetProperties();  
                   foreach (PropertyInfo GetProperty in columns)  
                   {  
                       Type colType = GetProperty.PropertyType;  
                       if ((colType.IsGenericType) && (colType.GetGenericTypeDefinition()  
                       == typeof(Nullable<>)))  
                       {  
                           colType = colType.GetGenericArguments()[0];  
                       }  
                       dt.Columns.Add(new DataColumn(GetProperty.Name, colType));  
                   }  
               } 
               DataRow dr = dt.NewRow();  
               foreach (PropertyInfo pinfo in columns)  
               {  
                   dr[pinfo.Name] = pinfo.GetValue(Record, null) == null ? DBNull.Value : pinfo.GetValue(Record, null);  
               }  
               dt.Rows.Add(dr);  
           }  
           return dt;  
       }
