C # loop syntax and their respective features

C # contains the following types of loops:

① While

② Do... while...

③

④ Foreach

 

No1.While Loop

Bool flag = true;

While (flag)

{

/* Do something */

If (Condition)

{

Flag = false;

}

}

The while LOOP checks the logical expression before each loop. The loop jump completely depends on the changes in the loop body. However, if the program has some problems in it, it will lead to an endless loop.

 

No2.do... while... loop

Similar to the while loop.

 

No3.for Loop

.

 

No4. foreach Loop

The foreach loop is mainly used to traverse the container type that implements IEnumerable. Both the array type and Common Containers implement this interface.

Foreach is preferred when designing to traverse containers or arrays.

However, the foreach statement has certain limitations, that is, it cannot assign values to the project, nor assign values to the internal members of the project through properties. However, it can call internal methods to assign values to internal members.
