How to Efficiently Convert Base 10 Numbers to Arbitrary Bases in .NET?

<.> In the .NET, the decimal number was converted to any advancement

Many developers need to quickly and effectively convert the decimal numbers into other progressive production. Although the .NET provides functions, it only supports 16, 10, 8, and 2nd -in. For more common conversion, solutions need to be customized.

A commonly used method includes the following steps: Convert.ToString(number, x)

Method:

Initialized results string: Use an empty string to store the conversion result.

Get target progress:
1. OK to be converted to the target progress. Traversing numbers:
traversing numbers, calculating the remaining number after the target is made.
2. Additional to the result string: Add the remainder (as a character from the inlet character set) to the result string.
3. Except numbers: Divide the numbers into the target and repeat steps 3-5 until the number becomes zero.
4. This method is simple and clear, and the efficiency is relatively high. However, in order to get the best performance, please consider the following: Performance enhancement:
5. Use array buffer:
Use array buffer cumulative result characters, not string connection.

Optimize the buffer size:

Select the appropriate buffer size according to the expected results length.

Reverse results string: After the array is filled, it reverses it to obtain the correct order order.

• Example implementation:
The following is the c# example of the algorithm, including the original method and optimization method:
• This optimization method can significantly improve the performance of large numbers or convert into a large number of characters.
