C#9 Structure Employee Information student performance

struct: the equivalent of a complex type that we define ourselves.

Int... Double float bool Char string DateTime array type

Most of the objects in life are complex objects.

How do I define a struct type?

In general, the definition of the structure should be placed outside the class or inside the class , try not to put in the inside of Main.

struct Custom type name

{

Public Variable type variable name ;  ......;  ......; ......;

}

For example :

struct Yuangong// custom data type. Information used to describe an employee.   

{

public string NO;

public string Name;

public int age;

public string Nation;

public bool Sex;

}

How do I define a variable with a custom type? Custom type name Variable = new custom type name ();

How do I use a variable of a custom type?

Variable . Child Variables = "XXXX"; Console.WriteLine ( variable name . Child Variables );

For example :

Define a variable of a custom type

Yuangong Zhangsan = new Yuangong ();

Assigning values to variables

zhangsan.no = "Y001";

Zhangsan.         Name = " Zhang San ";

Zhangsan. age = 22;

Zhangsan. Sex = true;

Zhangsan.  Nation = " han ";

to value a variable

Console.WriteLine (zhangsan.no+ "\ t" +zhangsan. Name+ "\ t" +zhangsan. Age);

Console.WriteLine (Zhangsan. nation+ "\ T" + (Zhangsan. "Sex?" male ":" female "));

Example 1:

struct Yuangong//custom data type. Information used to describe an employee.

{

public string NO;

public string Name;

public int age;

public string Nation;

public bool Sex;

Public Lianxifangshi Lianxi;

}

struct Lianxifangshi

{

public string QQ;

public string Weixin;

public string Email;

public string Telephone;

public string Address;

public string ZipCode;

}

Class Program

{

static void mai0n (string[] args)

{

Yuangong Zhangsan = new Yuangong ();

zhangsan.no = "Y001";

Zhangsan. Name = "Zhang San";

Zhangsan. age = 22;

Zhangsan. Sex = true;

Zhangsan. Nation = "Han";

Zhangsan. LIANXI.QQ = "434354546";

Zhangsan. Lianxi.weixin = "Zhang 33";

Zhangsan. Lianxi.email = "[Email protected]";

Zhangsan. lianxi.address = "Zhang Jia Hutong, Zhangdian District";

Zhangsan. Lianxi.zipcode = "25000";

Zhangsan. Lianxi.telephone = "";

Yuangong lisi = new Yuangong ();

lisi.no = "Y002";

Lisi. Name = "John Doe";

Lisi. Age = 25;

Lisi. Sex =false;

Lisi. Nation = "Hui";

Console.WriteLine ("********** Zhang San personal Information ***********");

Console.WriteLine (zhangsan.no+ "\ t" +zhangsan. Name+ "\ t" +zhangsan. Age);

Console.WriteLine (Zhangsan. nation+ "\ T" + (Zhangsan. "Sex?" Male ":" female "));

Console.WriteLine ("Contact information:");

Console.WriteLine (

"QQ:" + (Zhangsan. Lianxi.qq==null? " None ": Zhangsan. LIANXI.QQ) + "\ T"

+ ":" + (Zhangsan. Lianxi.weixin = = null? " None ": Zhangsan. lianxi.weixin) + "\ T"

+ "Mobile:" + (Zhangsan. Lianxi.telephone==null? " None ": Zhangsan. Lianxi.telephone) + "\ T"

+ "Mailbox:" + (Zhangsan. Lianxi.email==null? " None ": Zhangsan. Lianxi.email) + "\ T"

+ "Address:" +zhangsan. lianxi.address+ "\ t" +zhangsan. Lianxi.zipcode);

}

}

Example 2:

struct Xuesheng

{

public int Xuehao;

public string xingming;

public double Yuwen;

public double Shuxue;

public double Waiyu;

public double Zongfen;

public int Minci;

}

Class Class1

{

static void mai1n (string[] args)

{

Int[] A = new int[5];

Xuesheng[] s = new xuesheng[5];

Input

Shuru (s);

Sort

Paixu (s);

Fill in the rankings

XIEMINGCI (s);

Output display

Shuchu (s);

}

private static void Shuchu (xuesheng[] s)

{

for (int i = 0; i < s.length; i++)

{

Console.WriteLine (S[i]. Xuehao + "\ T" + s[i]. Xingming + "\ T" + s[i]. Yuwen + "\ T" + s[i]. Shuxue + "\ T"

+ S[i]. Waiyu + "\ T" + s[i]. Zongfen + "\ T" + s[i]. MINCI);

}

}

private static void Xiemingci (xuesheng[] s)

{

for (int i = 0; i < s.length; i++)

{

S[i]. Minci = i + 1;

}

}

private static void Paixu (xuesheng[] s)

{

for (int i = 1; I <= s.length-1; i++)

{

for (int j = 1; J <= S.length-i; j + +)

{

if (S[j]. Zongfen > S[j-1]. Zongfen)

{

Xuesheng temp = s[j];

S[J] = s[j-1];

S[J-1] = temp;

}

}

}

}

private static void Shuru (xuesheng[] s)

{

for (int i = 0; i < s.length; i++)

{

Console.WriteLine ("Entering section" + (i + 1) + "Information of students");

S[i]. Xuehao = i + 1;

Console.Write ("Name:");

S[i]. xingming = Console.ReadLine ();

Console.Write ("Language:");

S[i]. Yuwen = Convert.todouble (Console.ReadLine ());

Console.Write ("Mathematics:");

S[i]. Shuxue = Convert.todouble (Console.ReadLine ());

Console.Write ("Foreign Language:");

S[i]. Waiyu = Convert.todouble (Console.ReadLine ());

Score:

S[i]. Zongfen = S[i]. Yuwen + s[i]. Shuxue + s[i]. Waiyu;

}

}
