Find all substrings in a string using the substring() method in C#.
Suppose our string is -
Xyz
Loop through the length of the string and use the Substring function from the beginning to the end of the string -
for (int start = 0; start <= str.Length - i; start++) {
string substr = str.Substring(start, i);
Console.WriteLine(substr);
}The following is a C# program to find all substrings in a string.
Live Demo
using System;
class Demo {
static void Main() {
string str = "xyz";
for (int i = 1; i < str.Length; i++) {
for (int start = 0; start <= str.Length - i; start++) {
string substr = str.Substring(start, i);
Console.WriteLine(substr);
}
}
}
