C#将HashTable中键列表或值列表复制到一维数组的方法
本文实例讲述了C#将HashTable中键列表或值列表复制到一维数组的方法。分享给大家供大家参考。具体如下：
下面的示例说明如何将Hashtable中键的列表或值的列表复制到一维Array中。
usingSystem;
usingSystem.Collections;
publicclassSamplesHashtable{
publicstaticvoidMain(){
//CreatesandinitializesthesourceHashtable.
HashtablemySourceHT=newHashtable();
mySourceHT.Add("A","valueA");
mySourceHT.Add("B","valueB");
//Createsandinitializestheone-dimensionaltargetArray.
String[]myTargetArray=newString[15];
myTargetArray[0]="The";
myTargetArray[1]="quick";
myTargetArray[2]="brown";
myTargetArray[3]="fox";
myTargetArray[4]="jumped";
myTargetArray[5]="over";
myTargetArray[6]="the";
myTargetArray[7]="lazy";
myTargetArray[8]="dog";
//DisplaysthevaluesofthetargetArray.
Console.WriteLine("ThetargetArraycontainsthefollowingbefore:");
PrintValues(myTargetArray,'');
//CopiesthekeysinthesourceHashtabletothetargetHashtable,startingatindex6.
Console.WriteLine("Aftercopyingthekeys,startingatindex6:");
mySourceHT.Keys.CopyTo(myTargetArray,6);
//DisplaysthevaluesofthetargetArray.
PrintValues(myTargetArray,'');
//CopiesthevaluesinthesourceHashtabletothetargetHashtable,startingatindex6.
Console.WriteLine("Aftercopyingthevalues,startingatindex6:");
mySourceHT.Values.CopyTo(myTargetArray,6);
//DisplaysthevaluesofthetargetArray.
PrintValues(myTargetArray,'');
}
publicstaticvoidPrintValues(String[]myArr,charmySeparator){
for(inti=0;i<myArr.Length;i++)
Console.Write("{0}{1}",mySeparator,myArr[i]);
Console.WriteLine();
}
}
/*
