循环和字符串输出

本文关键字：输出 字符串 循环 | 更新日期: 2023-09-27 18:05:27

你好，我有以下代码:

static void CalcWordchange()
{
    List<string[]> l = new List<string[]>
        {
        new string[]{Question1, matcheditalian1},
        new string[]{"Sam", matcheditalian2},
        new string[]{"clozapine", matcheditalian3},
        new string[]{"flomax", matcheditalian4},
        new string[]{"toradol", matcheditalian5},
        };
    foreach (string[] a in l)
    {
        int cost = LevenshteinDistance.Compute(a[0], a[1]);
        errorString = String.Format("To change your input: 'n {0} 'n into the correct word: 'n {1} 'n you need to make: 'n {2} changes 'n ".Replace("'n",      Environment.NewLine),
            a[0],
            a[1],
            cost);
    }
}

每次单击按钮时，foreach循环中的文本运行并输出一个句子(列表中的最后一项)。我想要发生的是将所有5项输出到一个字符串中。

我已经添加了4个新的变量(errorString2, 3等)，但不知道如何输出。

感谢任何帮助，由于

循环和字符串输出

尝试使用StringBuilder对象收集所有部件。

StringBuilder buildString = new StringBuilder();
foreach (string[] a in l)
{
    int cost = LevenshteinDistance.Compute(a[0], a[1]);
    buildString.AppendFormat("To change your input: 'n {0} 'n into the correct word: 'n {1} 'n you need to make: 'n {2} changes 'n ".Replace("'n",      Environment.NewLine),
        a[0],
        a[1],
        cost);
}
errorString = buildString.ToString();

不如这样做:

 string finalOuput = string.empty;
 foreach (string[] a in l)
 {
  int cost = levelshteinDstance.Compute(a[0], a[1]);
  finalOutput += string.Format("To change your input: 'n {0} 'n into the correct word: 'n {1} 'n you need to make: 'n {2} changes 'n ".Replace("'n",      Environment.NewLine),
            a[0],
            a[1],
            cost);
    }
}

//显示finalOutput

创建List<string>保存输出:

var OutputList = new List<string>();
foreach (string[] a in l)
{
    errorString = ...
    OutputList.Add(errorString);
}
// output
foreach (var s in OutputList)
{
    Console.WriteLine(s);
}

或者你可以使用StringBuilder:

var outputS = new StringBuilder();
foreach (string[] a in l)
{
    errorstring = ...
    outputS.AppendLine(errorString);
}
Console.WriteLine(outputS.ToString());
