菜鸟送分：回车换行符替换问题
string tempStr = newStr.Replace((char)13, (char)0);
return tempStr.Replace((char)10, (char)0);
这样替换成了两个(char)0，怎样替换成一个(char)0？
我这样出错了：
string as = xxx
as=as.Replace((char)13&(char)10, (char)0);

错误提示：

Compiler Error Message: CS1502: The best overloaded method match for 'string.Replace(char, char)' has some invalid arguments

[解决办法]
return newStr.Replace("\r\n", "\0");
[解决办法]
那当然，谁让你替换成"\0"
你可以替换成空格或者别的字符看看。
