示例1: CompilationRelaxations
// Sample for String.IsInterned(String)
using System;
using System.Text;
using System.Runtime.CompilerServices;
// In the .NET Framework 2.0 the following attribute declaration allows you to
// avoid the use of the interning when you use NGEN.exe to compile an assembly
// to the native image cache.
[assembly: CompilationRelaxations(CompilationRelaxations.NoStringInterning)]
class Sample
{
public static void Main()
{
// String str1 is known at compile time, and is automatically interned.
String str1 = "abcd";
// Constructed string, str2, is not explicitly or automatically interned.
String str2 = new StringBuilder().Append("wx").Append("yz").ToString();
Console.WriteLine();
Test(1, str1);
Test(2, str2);
}
public static void Test(int sequence, String str)
{
Console.Write("{0}) The string, '", sequence);
String strInterned = String.IsInterned(str);
if (strInterned == null)
Console.WriteLine("{0}', is not interned.", str);
else
Console.WriteLine("{0}', is interned.", strInterned);
}
}输出：
1) The string, 'abcd', is interned. 2) The string, 'wxyz', is not interned. If you use NGEN.exe to compile the assembly to the native image cache, this example produces the following results: 1) The string, 'abcd', is not interned. 2) The string, 'wxyz', is not interned.
示例2: Main
//引入命名空间
using System;
public class Example
{
public static void Main()
{
string str1 = "a";
string str2 = str1 + "b";
string str3 = str2 + "c";
string[] strings = { "value", "part1" + "_" + "part2", str3,
String.Empty, null };
foreach (var value in strings) {
if (value == null) continue;
bool interned = String.IsInterned(value) != null;
if (interned)
Console.WriteLine("'{0}' is in the string intern pool.",
value);
else
Console.WriteLine("'{0}' is not in the string intern pool.",
value);
}
}
}输出：
'value' is in the string intern pool. 'part1_part2' is in the string intern pool. 'abc' is not in the string intern pool. '' is in the string intern pool.
