Two of these methods allow you to easily implement conversions between the various values of the system:
Convert.ToInt32 (string value, int frombase):
You can convert a string of different values into numbers, where the frombase parameter is in the form of 2, 8, 10, and 16:
If Convert.ToInt32 ("0010", 2) The result of execution is 2;
convert.tostring (int value, int tobase):
You can convert a number to a string format with different values, where the tobase parameter is in the form of 2, 8, 10, and 16:
If Convert.ToString (2,2) Executes the result is "0010"
Now we do a method to implement the string free conversion between the various systems: choose to convert it to a numeric type, and then convert it to the corresponding string in the system:
Copy Code code as follows:
public string convertstring (string value, int frombase, int tobase)
{
int intvalue = Convert.ToInt32 (value, frombase);
Return convert.tostring (Intvalue, tobase);
}

Where Frombase is the original format
Tobase is the format that will be converted
