Function Overloading is the same as the Chinese method name of the same class. The parameter list is different. The parameter list is different, including the number of parameters in the method or the parameter data type is different.

First, it is a common overload. You can modify the number and Data Type of parameters.

}
Void dowork (int intdata, float floatdata)
{
Console. WriteLine ("intdata: {0}, floatdata: {1}", intdata, floatdata );
}
Void dowork (float floatdata, int moreintdata)
{
Console. WriteLine ("floatdata: {0}, moreintdata: {1}", floatdata, moreintdata );
}
}
}

You can also assign default values to parameters for reload. Note that parameters without default values are written before, and parameters with default values are written after.

You can also specify the parameter value to reload.
