c# string foreach code example

Example 1: foreach syntax c#

var fibNumbers = new List<int> { 0, 1, 1, 2, 3, 5, 8, 13 };
int count = 0;
foreach (int element in fibNumbers)
{
    count++;
    Console.WriteLine($"Element #{count}: {element}");
}
Console.WriteLine($"Number of elements: {count}");

Example 2: foreach c#

var fibNumbers = new List<int> { 0, 1, 1, 2, 3, 5, 8, 13 };
int count = 0;
foreach (int element in fibNumbers)
{
    count++;
    Console.WriteLine($"Element #{count}: {element}");
}
Console.WriteLine($"Number of elements: {count}");

Example 3: c# iterate over string

// Regular Strings
string foo = "hello world", bar = string.Empty;

foreach(char c in foo){
    bar += c;
}

// StringBuilder
string foo = "hello world";
StringBuilder bar = new StringBuilder();

foreach (char c in foo)
{
    bar.Append(c);
}
