Patterns are the repeated decorative design. There is a simple code to write patterns in C#. We can write code to print different types of patterns like star pattern, character pattern and number pattern. Below are the various examples to print patterns of star, character and numeric values. These examples consist of loops or nested loops which is a loop inside for a loop. Patterns are a way of designing in sequence or in a logical manner. We can print triangles, pyramids, diamonds, and other symmetries.
Top 3 types of Patterns in C#
The top 3 types of patterns in c# are mentioned below.
1. Star Pattern
The following are examples to print star patterns.
Example #1

{
static void Main(string[] args)
{
int x, y, z;
for (x =6; x >= 1; x--)
{
for (y = 1; y < x; y++)
{
Console.Write(" ");
}
for (z = 6; z >= x; z--)
{
Console.Write("*");
}
Console.WriteLine();
}
Console.ReadLine();
}

Conclusion
So above are some examples of various types of patterns. We can print any type of pattern with some changes in the loops.
The above is the detailed content of Patterns in C#. For more information, please follow other related articles on the PHP Chinese website!
