Could anybody tell me how to convert greek number format to english, then I can use my application?

推荐答案

我希望您理解数字数据本身没有文化差异，但是如果数字形式的文本可能具有表示形式， .例如，这样的差异之一是小数点.如果是这个问题?

在这种情况下，您只需要读取某些特定区域性的数据即可.

您可以在文本阅读器读取和解析数据之前更改当前线程的区域性:

I hope you understand that the numeric data itself has no cultural difference, but the representation if the numbers in the form of text may have. One such difference is a decimal point, for example. If this the problem?

In this case, you only need to read data in some specific culture.

You can change the culture of a current thread before your text reader reads and parses the data:

System.Globalization.CultureInfo savedCulture = System.Threading.Thread.CurrentThread.CurrentCulture;
try {
   //the culture of Greek (Greece):
   System.Globalization.CultureInfo culture = new System.Globalization.CultureInfo("el-GR");
   System.Threading.Thread.CurrentThread.CurrentCulture = culture;
   //read and parse data in a usual way
} finally {
   System.Threading.Thread.CurrentThread.CurrentCulture = savedCulture;
}

本质上，所有将文本解析为数字数据时都将有所作为；因此，在细节层面上，您可以做

Essentially, all that makes a difference while parsing a text into a numeric data; so, on a detail level, you can do

// use the culture defined above as System.IFormatProvider
// as System.Globalization.CultureInfo implements System.IFormatProvider
double value = double.Parse(someText, culture); //will throw exception in the case of invalid format
// or
if (!double.TryParse(someText, out value)) { /* ... */ } //without throwing exception
// here, we assume someText representing a single number 

-SA

由于您只有10位数字，我认为您逐位读取文件，并将每个数字解析为等效的英文翻译.

Since you have only 10 digits, I would think you read the file digit by digit and parse each digit into its equivalent English translation.

您必须从字符串的后端开始.

You have to start from the back-end of the string.
