How to use the ToString() method in C#
Theodore Kelechukwu OnyejiakuWe can convert a Boolean, an integer, or a character, and so on to a string by using the ToString() method in C#.
Syntax
public override string ToString()
Parameters
This method doesn’t take any arguments.
Return value
This method returns a string as a result.
Code
In the code below, we will create some variables with different data types in C# and convert them to strings using the ToString() method.
// create class
class StringConverter
{
// main method
static void Main()
{
// create variables
int quantity = 20;
double price = 50.00;
char tag = 'T';
bool isFinished = false;
// convert them to strings
string a = quantity.ToString();
string b = price.ToString();
string c = tag.ToString();
string d = isFinished.ToString();
// print out converted values
System.Console.WriteLine(a);
System.Console.WriteLine(b);
System.Console.WriteLine(c);
System.Console.WriteLine(d);
}
}-
From the code above, all the variables created that are not strings, were all converted to a string by using the
ToString()method. -
In line 14,
quantity, which is an integer value, was converted to a string. -
In line 15,
price, which is adoubledata type, was converted to a string value usingToString(). -
