      {
          public string PropertyName { get; set; }
          public string VendorName { get; set; }
          public string VendorNumber { get; set; }
          public string InvoiceNumber { get; set; }
          public DateTime? InvoicePostDate { get; set; }
          public string UseTaxName { get; set; }
          public decimal UseTaxExemptAmount { get; set; }
          public decimal UseTaxAmount { get; set; }
          public decimal UseTaxNonExemptAmount { get; set; }
          public decimal InvoiceAmount { get; set; }           
      }
string Name= "Nath"

Can you show how you are populating the list.

List<PrintUTAccural> list = new List<PrintUTAccural>();
list.Add(new PrintUTAccural{ VendorName = "David", VendorNumber = "1"});
list.Add(new PrintUTAccural{ VendorName = "Nath", VendorNumber = "88"});
list.Add(new PrintUTAccural{ VendorName = "Thom", VendorNumber = "3"});
list.Add(new PrintUTAccural{ VendorName = "Wilson", VendorNumber = "4"});

string VenderNumber = list.Where(x => x.VendorName == "Nath").Select(x => x.VendorNumber).SingleOrDefault();

Console.WriteLine("Vendor Number: " + VenderNumber);

I did the above and your code worked fine.

It might be worth trying FirstOrDefault() instead of SingleOrDefault()?
