字符串比较

1、字符串长度
Java
String d = "ddd";
d.length();
C#
string str = "Hello World!";
Console.WriteLine(str.Length);
Console.ReadLine();
2、指定索引的字符
Java
public char charAt(int index)
C#
无
3、字符串比较
Java
public int compareTo(String anotherString)
public int compareToIgnoreCase(String str)
public boolean equals(Object anObject)
C#
public static int Compare( string strA, string strB )
string str = "Hello World!";
Console.WriteLine(str.CompareTo(str));
public bool Equals( string value )
public static bool Equals( string a, string b )
4、判断开头结尾
Java
public boolean startsWith(String prefix)
public boolean endsWith(String suffix)
C#
public bool EndsWith( string value )
public bool StartsWith( string value )

5、字符串大小写转换
Java
public String toUpperCase()
public String toLowerCase()
C#
public string ToLower()
public string ToUpper()
