Ant Java build：编译问题 - 将字符集从ISO-8859-1更改为UTF-8(Ant Java build: Compilation issue - Change of character set from ISO-8859-1 to UTF-8)
Ant Java build：编译问题 - 将字符集从ISO-8859-1更改为UTF-8(Ant Java build: Compilation issue - Change of character set from ISO-8859-1 to UTF-8)
位新的字符集编码格式。 我有一个ant构建脚本，它以ISO-8859-1格式编译我的java代码。 它工作正常。
阅读了几篇文章之后： 如何在Java中转换ISO-8859-1和UTF-8？
我已经将characterSet格式更改为UTF-8，因此编译问题开始了。
抛出的错误是：
[javac] TestEncoding.java (at line 11) [javac] case '?' : [javac] ^^^^^^^^我的建立脚本如下：
<javac compiler="org.eclipse.jdt.core.JDTCompilerAdapter" destdir="bin" debug="true" deprecation="on" encoding="iso-8859-1" source="1.6" target="1.6" debuglevel="lines,source" failonerror="false" errorProperty="buildFailed"> <compilerarg line="-warn:+raw" /> <compilerarg line="-warn:-serial" /> <compilerarg line="-log source/testapp/compileLog.xml" /> <src path="testapp" /> <classpath refid="application.classpath" /> </javac>我的一个有问题的课程中有以下代码：
public class TestEncoding { public static final String filterAccent(String s) { StringBuffer sb = new StringBuffer(); int n = s.length(); for (int i = 0; i < n; i++) { char c = s.charAt(i); switch (c) { case 'á': sb.append("a"); break; case 'à': sb.append("a"); break; case 'ã': sb.append("a"); break; case 'À': sb.append("A"); break; case 'â': sb.append("a"); break; case 'Â': sb.append("A"); break; case 'ä': sb.append("a"); break; case 'Ä': sb.append("A"); break; case 'å': sb.append("a"); break; case 'Å': sb.append("A"); break; case 'ç': sb.append("c"); break; case 'Ç': sb.append("C"); break; case 'é': sb.append("e"); break; case 'É': sb.append("E"); break; case 'è': sb.append("e"); break; case 'È': sb.append("E"); break; case 'ê': sb.append("e"); break; case 'Ê': sb.append("E"); break; case 'ë': sb.append("e"); break; case 'Ë': sb.append("E"); break; case 'í': sb.append("i"); break; case 'ì': sb.append("i"); break; case 'ï': sb.append("i"); break; case 'î': sb.append("i"); break; case 'Ï': sb.append("I"); break; default: sb.append(c); break; } } return sb.toString(); } }我也尝试将字符集更改为UTF-16，但这次它引发了不同的错误：

Bit new to character set encoding formats. I have a ant build script, that compiles my java code in ISO-8859-1 format. It was working fine.
After reading couple of articles: How do I convert between ISO-8859-1 and UTF-8 in Java?
I have changed the characterSet format to UTF-8, since then the compilation issues started.
Error thrown is:
[javac] TestEncoding.java (at line 11) [javac] case '?' : [javac] ^^^^^^^^My Build script has follows:
<javac compiler="org.eclipse.jdt.core.JDTCompilerAdapter" destdir="bin" debug="true" deprecation="on" encoding="iso-8859-1" source="1.6" target="1.6" debuglevel="lines,source" failonerror="false" errorProperty="buildFailed"> <compilerarg line="-warn:+raw" /> <compilerarg line="-warn:-serial" /> <compilerarg line="-log source/testapp/compileLog.xml" /> <src path="testapp" /> <classpath refid="application.classpath" /> </javac>One of my class that is having problems has following code in it:
public class TestEncoding { public static final String filterAccent(String s) { StringBuffer sb = new StringBuffer(); int n = s.length(); for (int i = 0; i < n; i++) { char c = s.charAt(i); switch (c) { case 'á': sb.append("a"); break; case 'à': sb.append("a"); break; case 'ã': sb.append("a"); break; case 'À': sb.append("A"); break; case 'â': sb.append("a"); break; case 'Â': sb.append("A"); break; case 'ä': sb.append("a"); break; case 'Ä': sb.append("A"); break; case 'å': sb.append("a"); break; case 'Å': sb.append("A"); break; case 'ç': sb.append("c"); break; case 'Ç': sb.append("C"); break; case 'é': sb.append("e"); break; case 'É': sb.append("E"); break; case 'è': sb.append("e"); break; case 'È': sb.append("E"); break; case 'ê': sb.append("e"); break; case 'Ê': sb.append("E"); break; case 'ë': sb.append("e"); break; case 'Ë': sb.append("E"); break; case 'í': sb.append("i"); break; case 'ì': sb.append("i"); break; case 'ï': sb.append("i"); break; case 'î': sb.append("i"); break; case 'Ï': sb.append("I"); break; default: sb.append(c); break; } } return sb.toString(); } }I have also tried to change the characterset to UTF-16, but this time it has thrown different errors:

我同意谢尔盖的评论，但你可以这样做：
var content = new List<List<string>> { new List<string>{ "book", "code", "columnToSum" }, new List<string>{ "abc", "1", "10" }, new List<string>{ "abc", "1", "5" }, new List<string>{ "cde", "1", "6" }, }; var headers = content.First(); var result = content.Skip(1) .GroupBy(s => new { Code = s[headers.IndexOf("code")], Book = s[headers.IndexOf("book")]}) .Select(g => new { Book = g.Key.Book, Code = g.Key.Code, Total = g.Select(s => int.Parse(s[headers.IndexOf("columnToSum")])).Sum() });哪个回报：
{ Book = abc, Code = 1, Total = 15 } { Book = cde, Code = 1, Total = 6 }I agree with Sergey's comment but You could do something like this:
var content = new List<List<string>> { new List<string>{ "book", "code", "columnToSum" }, new List<string>{ "abc", "1", "10" }, new List<string>{ "abc", "1", "5" }, new List<string>{ "cde", "1", "6" }, }; var headers = content.First(); var result = content.Skip(1) .GroupBy(s => new { Code = s[headers.IndexOf("code")], Book = s[headers.IndexOf("book")]}) .Select(g => new { Book = g.Key.Book, Code = g.Key.Code, Total = g.Select(s => int.Parse(s[headers.IndexOf("columnToSum")])).Sum() });Which returns:
{ Book = abc, Code = 1, Total = 15 } { Book = cde, Code = 1, Total = 6 }
