Multiple Where clause in C# Linq
Filter collections using Where clause in C#. A single query expression may have multiple where clauses.
Firstly, set a collection −
IList<Employee> employee = new List<Employee>() {
new Employee() { EmpID = 1, EmpName = "Tom", EmpMarks = 90, Rank = 8} ,
new Employee() { EmpID = 2, EmpName = "Anne", EmpMarks = 60, Rank = 21 } ,
new Employee() { EmpID = 3, EmpName = "Jack", EmpMarks = 76, Rank = 18 } ,
new Employee() { EmpID = 4, EmpName = "Amy" , EmpMarks = 67, Rank = 20} ,
};Now, let’s use multiple where clause to get the employee with rank more than 5 and less than 10.
var res = from e in employee where e.Rank > 5 where e.Rank < 10 select e;
The following is the code −
Example
using System;
using System.Linq;
using System.Collections.Generic;
public class Demo {
public static void Main() {
IList<Employee> employee = new List<Employee>() {
new Employee() { EmpID = 1, EmpName = "Tom", EmpMarks = 90, Rank = 8} ,
new Employee() { EmpID = 2, EmpName = "Anne", EmpMarks = 60, Rank = 21 } ,
new Employee() { EmpID = 3, EmpName = "Jack", EmpMarks = 76, Rank = 18 } ,
new Employee() { EmpID = 4, EmpName = "Amy" , EmpMarks = 67, Rank = 20} ,
};
var res = from e in employee
where e.Rank > 5
where e.Rank < 10
select e;
foreach (var emp in res) {
Console.WriteLine("Name: "+emp.EmpName);
Console.WriteLine("Marks: "+emp.EmpMarks);
}
}
}
public class Employee {
public int EmpID { get; set; }
public string EmpName { get; set; }
public int EmpMarks { get; set; }
public int Rank { get; set; }
}Output
Name: Tom Marks: 90
