问题描述

我似乎无法弄清楚如何将ISO-8859-1字符(例如é)转换为实体编号为é.

I can't seem to figure out how to convert ISO-8859-1 characters, such as é, to it's entity number being é.

我希望能够使用一个字符串，例如:"SteelDécor"

I want to be able to take a string, such as: "Steel Décor"

并将其转换为:"Steel D é cor"

and have it converted to: "Steel Décor"

推荐答案

假定您不关心HTML中特殊的HTML编码字符(例如<，&等)，则可以通过一个简单的循环该字符串将起作用:

Assuming you don't care about HTML-encoding characters that are special in HTML (e.g., <, &, etc.), a simple loop over the string will work:

string input = "Steel Décor";
StringBuilder output = new StringBuilder();
foreach (char ch in input)
{
    if (ch > 0x7F)
        output.AppendFormat("&#{0};", (int) ch);
    else
        output.Append(ch);
}
// output.ToString() == "Steel Décor"

根据您的确切需求，可能需要更改if语句以转义字符< 0x20或非字母数字等.

The if statement may need to be changed to also escape characters < 0x20, or non-alphanumeric, etc., depending on your exact needs.
