我想转换writen在一个字符串到其整数值二进制数。

I would like to convert a binary number writen in a String into its integer value.

例如：

string input = "0101";
int output = convert(input);

输出应等于 5

编辑：这真是小巫见大巫有人问，因为我有另外的错误，在我的code不使我看到，皈依是不是我的问题。

This really trivial question was asked because I had another bug in my code not enabling me to see that the convertion was not my problem.

推荐答案

Convert.ToInt32（字符串，的Int32 ）允许您指定的基地：

int output = Convert.ToInt32(input, 2);
