C# reuses the + for string concatenation.
using System;
class Program
{
static void Main(string[] args)
{
string s1 = "abc";
string s2 = "rntsoft.com";
string s3 = s1 + s2;
Console.WriteLine(s3);
}
}
The output:
abcrntsoft.com
We can use the operator + to append other types to a string type.
using System;
class Program
{
static void Main(string[] args)
{
string s1 = "abc";
string s2 = s1 + 5;
Console.WriteLine(s2);
}
}
The output:
abc5
Be careful when appending more than one variables to a string.
using System;
class Program
{
static void Main(string[] args)
{
string s1 = "abc";
string s2 = s1 + 5 + 5;
Console.WriteLine(s2);
}
}
The output:
abc55
To get the result we want, we have to do the math first.
using System;
class Program
{
static void Main(string[] args)
{
string s1 = "abc";
string s2 = s1 + (5 + 5);
Console.WriteLine(s2);
}
}
The output:
abc10
