C# 创建要在messagebox中显示的返回结果数组

我有一个方法，它向用户返回一个显示结果的messagebox。但对于多个结果，每个结果都会显示一个消息窗口。我如何创建它，以便将结果放入一个数组中，然后在最后将所有结果显示在一个messagebox中给用户

 foreach (KeyValuePair<string, int> kvp in Comparer)
            {
                if (kvp.Value != 0)
                {
                    mismatches++;
                    string InWhich = kvp.Value > 0 ? firstFile : secondFile;
                    MessageBox.Show("Extra value \n"+kvp.Key+" \nfound in file " + InWhich);
                    if (Math.Abs(kvp.Value) != 1)
                        MessageBox.Show( Math.Abs(kvp.Value)+ "times");
                }
            }

使用StringBuilder在循环中构建字符串，如下所示：

System.Text.StringBuilder theStringBuilder = new System.Text.StringBuilder();
foreach (KeyValuePair<string, int> kvp in Comparer)
{
    if (kvp.Value != 0)
    {
        mismatches++;
        string InWhich = kvp.Value > 0 ? firstFile : secondFile;
        theStringBuilder.AppendLine("Extra value \n"+kvp.Key+" \nfound in file " + InWhich);
        if (Math.Abs(kvp.Value) != 1)
            theStringBuilder.AppendLine( Math.Abs(kvp.Value)+ "times");
        }
    }
}

// Display all results in message box
MessageBox.Show(theStringBuilder.ToString());

var firstFileChanges = new List<string>();
var secondFileChanges = new List<string>();

System.Text.StringBuilder theStringBuilder = new System.Text.StringBuilder();
foreach (KeyValuePair<string, int> kvp in Comparer)
{
    if (kvp.Value != 0)
    {
        mismatches++;
        string InWhich = kvp.Value > 0 ? firstFile : secondFile;

        if(InWhich == firstFile)
        {
            firstFileChanges.Add(kvp.Key);
        }
        else 
        {
            secondFileChanges.Add(kvp.Key);
        }
    }
}

if(firstFileChanges.Count > 0 )
{
    theStringBuilder.Append("First file changes: ");

    int counter1 = 0;
    foreach(string change1 in firstFileChanges)
    {
        if(counter1 > 0)
        {
            theStringBuilder.Append(", ");
        }

        theStringBuilder.Append(change1);

        counter1 += 1;
    }

    theStringBuilder.AppendLine();
}

if(secondFileChanges.Count > 0 )
{
    theStringBuilder.Append("Second file changes: ");

    int counter2 = 0;
    foreach(string change2 in secondFileChanges)
    {
        if(counter2 > 0)
        {
            theStringBuilder.Append(", ");
        }

        theStringBuilder.Append(change2);

        counter2 += 1;
    }
}

MessageBox.Show(theStringBuilder.ToString());

更新：

要存储每个文件的更改，请使用如下列表：

System.Text.StringBuilder theStringBuilder = new System.Text.StringBuilder();
foreach (KeyValuePair<string, int> kvp in Comparer)
{
    if (kvp.Value != 0)
    {
        mismatches++;
        string InWhich = kvp.Value > 0 ? firstFile : secondFile;
        theStringBuilder.AppendLine("Extra value \n"+kvp.Key+" \nfound in file " + InWhich);
        if (Math.Abs(kvp.Value) != 1)
            theStringBuilder.AppendLine( Math.Abs(kvp.Value)+ "times");
        }
    }
}

// Display all results in message box
MessageBox.Show(theStringBuilder.ToString());

var firstFileChanges = new List<string>();
var secondFileChanges = new List<string>();

System.Text.StringBuilder theStringBuilder = new System.Text.StringBuilder();
foreach (KeyValuePair<string, int> kvp in Comparer)
{
    if (kvp.Value != 0)
    {
        mismatches++;
        string InWhich = kvp.Value > 0 ? firstFile : secondFile;

        if(InWhich == firstFile)
        {
            firstFileChanges.Add(kvp.Key);
        }
        else 
        {
            secondFileChanges.Add(kvp.Key);
        }
    }
}

if(firstFileChanges.Count > 0 )
{
    theStringBuilder.Append("First file changes: ");

    int counter1 = 0;
    foreach(string change1 in firstFileChanges)
    {
        if(counter1 > 0)
        {
            theStringBuilder.Append(", ");
        }

        theStringBuilder.Append(change1);

        counter1 += 1;
    }

    theStringBuilder.AppendLine();
}

if(secondFileChanges.Count > 0 )
{
    theStringBuilder.Append("Second file changes: ");

    int counter2 = 0;

您可以按如下方式使用StringBuilder

StringBuilder sb = new StringBuilder();
foreach (KeyValuePair<string, int> kvp in Comparer)
{
    if (kvp.Value != 0)
    {
        mismatches++;
        string InWhich = kvp.Value > 0 ? firstFile : secondFile;
        sb.AppendLine("Extra value \n" + kvp.Key + " \nfound in file " + InWhich + (Math.Abs(kvp.Value) != 1 ? ("\n" + Math.Abs(kvp.Value) + "times") : string.Empty)); 
    }
}
MessageBox.Show(sb.ToString());

您可以按如下方式使用StringBuilder

StringBuilder sb = new StringBuilder();
foreach (KeyValuePair<string, int> kvp in Comparer)
{
    if (kvp.Value != 0)
    {
        mismatches++;
        string InWhich = kvp.Value > 0 ? firstFile : secondFile;
        sb.AppendLine("Extra value \n" + kvp.Key + " \nfound in file " + InWhich + (Math.Abs(kvp.Value) != 1 ? ("\n" + Math.Abs(kvp.Value) + "times") : string.Empty)); 
    }
}
MessageBox.Show(sb.ToString());

如果我想对某个文件添加更改，我是否也可以为其创建stringbuilder？所以我没有得到文件一个增加2，文件一个增加狗。。。并将其添加一个文件：2，狗@Masriyah-当然，您可以有多个StringBuilder，但我不确定您对某个文件的更改是什么意思？这里我有两个文件，因此对第一个文件或第二个文件进行更改。因此，如果对第一个文件所做的更改，它将一次性声明第一个文件，并列出该文件中所做的所有更改。与其命名文件，不如多次显示更改和相同的文件名参见更新：回答您提出的一种方法。您是明星！感谢bunchif，我想给某个文件添加一个更改，我可以为它创建一个stringbuilder吗？所以我没有得到文件一个增加2，文件一个增加狗。。。并将其添加一个文件：2，狗@Masriyah-当然，您可以有多个StringBuilder，但我不确定您对某个文件的更改是什么意思？这里我有两个文件，因此对第一个文件或第二个文件进行更改。因此，如果对第一个文件所做的更改，它将一次性声明第一个文件，并列出该文件中所做的所有更改。与其命名文件，不如多次显示更改和相同的文件名参见更新：回答您提出的一种方法。您是明星！谢谢一个bunchi得到一个错误，说明我不能像linq那样从字符串转换到boolI，我会试试看。我得到一个错误，说明我不能像linq那样从字符串转换到boolI，我会试试看
