}
这个中的'错误信息函数是什么意思'
望高手指点

char 可以隐式转换为 ushort、int、uint、long、ulong、float、double 或 decimal。但是，不存在从其他类型到 char 类型的隐式转换。
system.char 类型提供几个处理 char 值的静态方法。
public static void main() {
char cha = 'a';
char ch1 = '1';
string str = "test string";
console.writeline(cha.compareto('b')); // output: "-1" (meaning 'a' is 1 less than 'b')
console.writeline(cha.equals('a')); // output: "true" console.writeline(char.getnumericvalue(ch1)); // output: "1"
console.writeline(char.iscontrol('\t')); // output: "true"
console.writeline(char.isdigit(ch1)); // output: "true"
console.writeline(char.isletter(',')); // output: "false"
console.writeline(char.islower('u')); // output: "true"
console.writeline(char.isnumber(ch1)); // output: "true"
console.writeline(char.ispunctuation('.')); // output: "true"
console.writeline(char.isseparator(str, 4)); // output: "true"
console.writeline(char.issymbol('+')); // output: "true"
console.writeline(char.iswhitespace(str, 4)); // output: "true"
console.writeline(char.parse("s")); // output: "s"
console.writeline(char.tolower('m')); // output: "m"
console.writeline('x'.tostring()); // output: "x"
}
以上都是char的一些常用的方法，可以用来判断输入的字符是否是数字或者字母，或者判断大小写都可以，我最新做的一个项目就用到了，希望对楼主有用，我是学c#的
