字符串数组到整数数组的转换 [英] String Array to Int Array Convertion

问题描述

你好，

我正在尝试使用以下代码将字符串数组转换为int数组:

Hello,

I am trying to convert a string array to int array using the following code:

stringArray[i, 0] = (Reader["Test"].ToString());
stringArray[i, 1] = (Reader["Test1"].ToString());
stringArray[i, 2] = (Reader["Test2"].ToString());

int toInt0 = Int32.Parse(stringArray[i, 0]);
int toInt1 = Int32.Parse(stringArray[i, 1]);
int toInt2 = Int32.Parse(stringArray[i, 2]);

intArray[i, 0] = toInt0;
intArray[i, 1] = toInt1;
intArray[i, 2] = toInt2;

我收到以下错误:

System.FormatException:输入字符串的格式不正确.
在System.Number.StringToNumber(String str，NumberStyles选项，NumberBuffer&数字，NumberFormatInfo信息，布尔值parseDecimal)
在System.Number.ParseInt32(String s，NumberStyles样式，NumberFormatInfo信息)
在System.Int32.Parse(String s)
在C:\ Users \ Dave \ Documents \ Visual Studio 2010 \ Projects \ Book \ Form1.cs:line 603中的Book.button1.test()处捕获到异常.

我该怎么解决?

谢谢，
Dave

I get the following error:

System.FormatException: Input string was not in a correct format.
at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal)
at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info)
at System.Int32.Parse(String s)
at Book.button1.test() in C:\Users\Dave\Documents\Visual Studio 2010\Projects\Book\Form1.cs:line 603 Exception caught.

What should i fix ?

Thanks,
Dave

推荐答案

您的代码正确.
这就是它:格式不正确的字符串.

如果Parse的参数是"-33321"，它将返回相应的整数值；如果它是"blah-blah"，您还能期望什么?不要使用TryParse，将其保留在代码中，使用调试器，然后找到"blah-blah"在字符串数组中的位置.

如果仍然需要帮助，请问一个后续问题，但向您显示数据和编写字符串的代码，而不是转换为整数.

重要！请不要将其发布为问题(常见错误)，请使用改进答案"，在其他情况下，请使用添加评论".

This is expected; your code is correct.
This what it is: string in not in correct format.

If the argument of Parse is "-33321", it will return correspondent integer value, if it is "blah-blah", what else could you expect? Don''t use TryParse, keep it as it is now in your code, use debugger and find where "blah-blah" gets in your string array.

If you still need help, ask a follow-up question, but show you data and the code writing your string, not converting into integers.
