The jQuery method is very convenient to use, which can simplify statements and make the code clear and concise. So can C# class methods also implement similar functions? Based on this doubt, I studied the source code of jQuery and found that the function method that requires method concatenation can finally return to the object itself. Since javascript is OK, C# should be OK too.
For verification, write a jQPerson class, and then use method combo to set its ID, Name, Age and other properties. Please see the following code:
using System;
using ;
using ;
using ;
using ;
namespace CSharpMethodLikeJQuery
{
public class jQPerson
{
string Id { set; get; }
string Name { set; get; }
int Age { set; get; }
string Sex { set; get; }
string Info { set; get; }
public jQPerson()
{
}
/// <summary>
/// Set the ID, return this, that is, jQPerson instance /// </summary>
/// <param name="Id"></param>
/// <returns></returns>
public jQPerson setId(string Id)
{
= Id;
return this;
}
/// <summary>
/// Return this, i.e. jQPerson instance /// </summary>
/// <param name="name"></param>
/// <returns></returns>
public jQPerson setName(string name)
{
= name;
return this;
}
/// <summary>
/// Return this, i.e. jQPerson instance /// </summary>
/// <param name="age"></param>
/// <returns></returns>
public jQPerson setAge(int age)
{
= age;
return this;
}
/// <summary>
/// Return this, i.e. jQPerson instance /// </summary>
/// <param name="sex"></param>
/// <returns></returns>
public jQPerson setSex(string sex)
{
= sex;
return this;
}
/// <summary>
/// Return this, i.e. jQPerson instance /// </summary>
/// <param name="info"></param>
/// <returns></returns>
public jQPerson setInfo(string info)
{
= info;
return this;
}
/// <summary>
/// tostring output key-value pair information /// </summary>
/// <returns></returns>
public string toString()
{
return ("Id:{0},Name:{1},Age:{2},Sex:{3},Info:{4}", , , , , );
}
}
}
Then you can test the above to see if the method junction takes effect:
/// <summary>
///toString test ///</summary>
[TestMethod()]
public void toStringTest()
{
jQPerson target = new jQPerson();
("2")
.setName("jack")
.setAge(26)
.setSex("man")
.setInfo("ok");
string expected = "Id:2,Name:jack,Age:26,Sex:man,Info:ok";
string actual;
actual = ();
(expected, actual);
//("Verify the correctness of this test method."); }
From the above operations, we can see that the method connection function does make the code intuitive and concise, and increases readability. You might as well give it a try.
