示例1: Main
//引入命名空间
using System;
public class Example
{
public unsafe static void Main()
{
string value = "This is the first sentence" + ".";
fixed (char* start = value)
{
value = String.Concat(value, "This is the second sentence. ");
fixed (char* current = value)
{
Console.WriteLine(start == current);
}
}
}
}输出：
False
示例2: Main
//引入命名空间
using System;
using System.Text;
public sealed class App
{
static void Main()
{
// Create a StringBuilder that expects to hold 50 characters.
// Initialize the StringBuilder with "ABC".
StringBuilder sb = new StringBuilder("ABC", 50);
// Append three characters (D, E, and F) to the end of the StringBuilder.
sb.Append(new char[] { 'D', 'E', 'F' });
// Append a format string to the end of the StringBuilder.
sb.AppendFormat("GHI{0}{1}", 'J', 'k');
// Display the number of characters in the StringBuilder and its string.
Console.WriteLine("{0} chars: {1}", sb.Length, sb.ToString());
// Insert a string at the beginning of the StringBuilder.
sb.Insert(0, "Alphabet: ");
// Replace all lowercase k's with uppercase K's.
sb.Replace('k', 'K');
// Display the number of characters in the StringBuilder and its string.
Console.WriteLine("{0} chars: {1}", sb.Length, sb.ToString());
}
}输出：
11 chars: ABCDEFGHIJk 21 chars: Alphabet: ABCDEFGHIJK
示例3: new StringBuilder()
//引入命名空间
using System;
using System.Text;
class MainClass
{
public static void Main()
{
StringBuilder sb = new StringBuilder();
Type t6 = sb.GetType();
}
}
