C# Trim() 方法使用实例
语法
public string Trim (); public string Trim (params char[] trimChars);
在上面，trimChars参数是一个要删除的Unicode字符数组，或者为null。
示例
using System;
using System.Globalization;
public class Demo {
public static void Main(String[] args) {
string str1 = " JackSparrow!";
string str2 = " @#$PQRSTUV!";
Console.WriteLine("String1 = "+str1);
Console.WriteLine("String1 (修剪后) = "+str1.Trim());
Console.WriteLine("String1 转换为大写= "+str1.ToUpper(new CultureInfo("en-US", false)));
Console.WriteLine("String1子字符串从索引4 = " + str1.Substring(2, 2));
Console.WriteLine("\n\nString2 = "+str2);
Console.WriteLine("String2 转换为大写= "+str2.ToUpper(new CultureInfo("en-US", false)));
Console.WriteLine("String2子字符串从索引5 = " + str2.Substring(0, 5));
}
}输出结果
String1 = JackSparrow! String1 (修剪后) = JackSparrow! String1 转换为大写= JACKSPARROW! String1子字符串从索引4 = String2 = @#$PQRSTUV! String2 转换为大写= @#$PQRSTUV! String2子字符串从索引5 = @
示例
using System;
public class Demo {
public static void Main(String[] args) {
string str = "JackSparrow!";
char[] arr = { 'J', 'a'};
Console.WriteLine("String = "+str);
Console.WriteLine("String (修剪后) = " + str.Trim(arr));
}
}输出结果
String = JackSparrow! String (修剪后) = ckSparrow!
