通过lambda表达式从列表中选择一个值 [英] select a single value from a list through lambda expression

问题描述

我有一个班级列表

  public   class  PrintUTAccural 
 {
  public   string  PropertyName {获得;  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 名称=   Nath 

我必须通过lambda表达式从这个列表中找到一个名字Nath然后我如何得到它。

  string  VenderNumber = UtAccuralLstForComp.Where（x = >  x.VendorName == Name）.Select（x = >  x.VendorNumber）.SingleOrDefault（）; 

i我正在使用此但没有获得价值

解决方案

的字符串VenderNumber = UtAccuralLstForComp.Where（X => x.VendorName ==名称）。.SingleOrDefault（）VENDORNAME 

I have a list of class

      public class PrintUTAccural
      {
          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"

and i have to find a name "Nath" from this list through lambda expression then how i get it.

string VenderNumber = UtAccuralLstForComp.Where(x => x.VendorName == Name).Select(x => x.VendorNumber).SingleOrDefault();

i am using this but didn't get value

[Edit]Code block added[/Edit]

解决方案

string VenderNumber = UtAccuralLstForComp.Where(x => x.VendorName == Name).SingleOrDefault().VendorName
