法律研究检查 C# 中的 StringDictionary 是否已同步
若要检查 StringDictionary 是否已同步，代码如下 −
示例
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main() {
StringDictionary strDict1 = new StringDictionary();
strDict1.Add("A", "John");
strDict1.Add("B", "Andy");
strDict1.Add("C", "Tim");
strDict1.Add("D", "Ryan");
strDict1.Add("E", "Kevin");
strDict1.Add("F", "Katie");
strDict1.Add("G", "Brad");
Console.WriteLine("StringDictionary1 elements...");
foreach(DictionaryEntry de in strDict1) {
Console.WriteLine(de.Key + " " + de.Value);
}
StringDictionary strDict2 = new StringDictionary();
strDict2.Add("1", "A");
strDict2.Add("2", "B");
strDict2.Add("3", "C");
strDict2.Add("4", "D");
strDict2.Add("5", "E");
Console.WriteLine("
StringDictionary2 key-value pairs...");
IEnumerator demoEnum = strDict2.GetEnumerator();
DictionaryEntry d;
while (demoEnum.MoveNext()) {
d = (DictionaryEntry)demoEnum.Current;
Console.WriteLine("Key = " + d.Key + ", Value = " + d.Value);
}
Console.WriteLine("Is the StringDictionary2 synchronized? = "+strDict2.IsSynchronized);
}
}输出
这将产生以下输出 −
StringDictionary1 elements... a John b Andy c Tim d Ryan e Kevin f Katie g Brad StringDictionary2 key-value pairs... Key = 1, Value = A Key = 2, Value = B Key = 3, Value = C Key = 4, Value = D Key = 5, Value = E Is the StringDictionary2 synchronized? = False
示例
让我们看另一个示例 −
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main() {
StringDictionary strDict = new StringDictionary();
strDict.Add("One", "Laptop");
strDict.Add("Two", "Desktop");
strDict.Add("Three", "Earphone");
strDict.Add("Four", "Speaker");
strDict.Add("Five", "HardDisk");
strDict.Add("Six", "SSD");
strDict.Add("Seven", "HardDisk");
Console.WriteLine("StringDictionary key-value pairs...");
IEnumerator demoEnum = strDict.GetEnumerator();
DictionaryEntry d;
while (demoEnum.MoveNext()) {
d = (DictionaryEntry)demoEnum.Current;
Console.WriteLine("Key = " + d.Key + ", Value = " + d.Value);
}
Console.WriteLine("Is StringDictionary synchronized? = "+strDict.IsSynchronized);
}
}输出
这将产生以下输出 −
StringDictionary key-value pairs... Key = five, Value = HardDisk Key = one, Value = Laptop Key = four, Value = Speaker Key = three, Value = Earphone Key = seven, Value = HardDisk Key = six, Value = SSD Key = two, Value = Desktop Is StringDictionary synchronized? = False
