将长字符串转换为整数 [英] Convert a long string to an integer

问题描述

你好，

我需要将长度等于24的字符串转换为整数.

Convert.ToInt32()对我不起作用，它引发以下错误:
对于Int32，值太大或太小.


我尝试了Convert.ToInt64()，它显示了相同的错误.

我需要此转换以进行数值比较.转换不必是整数类型.

任何想法如何解决这个问题?

谢谢

Hello,

I need to convert a string of length equals to 24 to an integer.

Convert.ToInt32()isn''t working for me, its throwing the following error:
Value was either too large or too small for an Int32.


I tried Convert.ToInt64() and it showed the same error.

I need this conversion for numerical comparisons. The conversion doesn''t need to be to an integer type.

Any idea how to resolve this issue?

Thank you

推荐答案

您可以尝试使用 C# BigInteger类 [ ^ ].

You could try something like the C# BigInteger Class[^].

您所指的是以下内容:

C#
int @int = int.Parse("123456789009876543211234");

VB.NET
Dim int As Integer = Integer.Parse("123456789009876543211234")

Is this what your referring to:

C#
int @int = int.Parse("123456789009876543211234");

VB.NET
Dim int As Integer = Integer.Parse("123456789009876543211234")

将其转换为双精度

Convert it to a double

string test = "0123456789012345678901234567890";

double dTest = Convert.ToDouble(test);

这会产生1.2345678901234568E+29精度问题，但是...

this will produce 1.2345678901234568E+29 precision could be a problem however...
