Method/Function Overloading in C#

Method overloading is a process in which we create the method with the same name with different parameter.
There are three types of method overloading in c# which is as follows.

1. Number of Parameter- in number of parameter we change the count of parameter to the method of same name.

For example
Public int sum(int x, int y)
{
Return x+y;
}
Public  int sum(int x, int y, int z)
{
 Return x=y+z;
}

2. Data Type of Parameter-we will simply change the data type of parameter passing to the method of same name.

public int sum(int x , int y)
{
 Return x+y;
}
Public string sum(string x, string y)
{
Return x+y;
}

3. Sequence of Parameter- In the third rule of method overloading we can change the sequence of parameter of same method.

Example
public string sum(string x, int y)
{
Return x+y;
}
Note - Return type does not bother in method overloading.
