C# - 用 RichTextbox 数据替换 ListBox 中的部分字符串

Question

我有一个标有placementTwoListBox 的列表框，我在其中加载了数据。 PlacementTwoListBox 如下所示：

placementTwoListBox:

U3      IC-00276G   236.135  198.644  90   
U12     IC-00270G   250.610  201.594  0    
J1      INT-00112G  269.665  179.894  180  
J2      INT-00112G  269.665  198.144  180  
J6      INT-00113G  227.905  174.994  180  
J3      INT-00113G  227.905  203.244  180  
U13     EXCLUDES    242.210  181.294  180

我还有 两个 RichTextBox 标记为calculatedXRichTextBox 和calculatedYRichTextBox。它们看起来像这样：

calculatedXRichTextBox:

246.135
260.610
279.665
279.665
237.905
237.905
252.210

calculatedYRichTextBox:

298.644
301.594
279.894
298.144
274.994
303.244
281.294

我正在尝试用 calculatedXRichTextBox 中的值替换 placementTwoListBox 的 第 3 列 中的值并替换这些值在 placementTwoListBox 的 第 4 列 中使用 calculatedYRichTextBox 中的值来获得最终结果（并将其放回原ListBox)的：

placementTwoListBox （更新）：

U3      IC-00276G   246.135  298.644  90   
U12     IC-00270G   260.610  301.594  0    
J1      INT-00112G  279.665  279.894  180  
J2      INT-00112G  279.665  298.144  180  
J6      INT-00113G  237.905  274.994  180  
J3      INT-00113G  237.905  303.244  180  
U13     EXCLUDES    252.210  281.294  180

• 有人知道如何实现吗？

编辑：

使用这两个时： @CrazyDart

calculatedXRichTextBox:

758.135
772.61
791.665
791.665
749.905
749.905
764.21

calculatedYRichTextBox:

-301.356
-298.406
-320.106
-301.856
-325.006
-296.756
-318.706

placementTwoListBox 看起来像这样：

U3      IC-00276G   758.135  -301.356666666  90   
U12     IC-00270G    772.61  -298.40666666  0    
J1      INT-00112G  791.665  -320.1066666  180  
J2      INT-00112G  791.665  -301.856666  180  
J6      INT-00113G  749.905  -325.00666  180  
J3      INT-00113G  749.905  -296.7566  180  
U13     EXCLUDES     764.21  -318.706  180  

Answer 1

这段代码是从placementTwoListBox中填充calculatedXRichTextBox和calculatedYRichTextBox：

string[] lines = new string[placementTwoListBox.Items.Count];

for (int itemIndex = 0; itemIndex < lines.Length; itemIndex++)
{ 
    lines[itemIndex] = placementTwoListBox.Items[itemIndex].ToString();
}

List<string> calculatedXLines = new List<string>();//to fill calculatedXRichTextBox
List<string> calculatedYLines = new List<string>();//to fill calculatedYRichTextBox

foreach (string line in lines)
{
    string[] items = line.Split(new string[] { "\t", " " }, 
        StringSplitOptions.RemoveEmptyEntires);

    if (items.Length > 2)
    {
        calculatedXLines.Add(items[2]);
        calculatedYLines.Add(items[3]);
    }
}

//add them to the calculatedYRichTextBox and the placementTwoListBox
calculatedXRichTextBox.Text = string.Join("\n", calculatedXLines); 
calculatedYRichTextBox.Text = string.Join("\n", calculatedYLines); 

编辑：回答问题：

string[] calculatedXLines = calculatedXRichTextBox.Text.Split(new string[] { "\n", "\r" },

StringSplitOptions.RemoveEmptyEntries);

string[] calculatedYLines = calculatedYRichTextBox.Text.Split(new string[] { "\n", "\r" },
    StringSplitOptions.RemoveEmptyEntries);

string[] lines = new string[placementTwoListBox.Items.Count];

for (int itemIndex = 0; itemIndex < lines.Length; itemIndex++)
{ 
    lines[itemIndex] = placementTwoListBox.Items[itemIndex].ToString();
}

List<string[]> newLines = new List<string[]>();

for (int lineIndex = 0; lineIndex < lines.Length; lineIndex++)
{
    string[] items = lines[lineIndex].Split(new string[] { " ", "\t" },
        StringSplitOptions.RemoveEmptyEntries);

    items[2] = calculatedXLines[lineIndex];
    items[3] = calculatedYLines[lineIndex];

    newLines.Add(items);
}

//represents your data on the `placementTwoListBox`:
placementTwoListBox.Items.Clear();
foreach (string[] lineItems in newLines)
{
    placementTwoListBox.Items.Add(string.Join("\t", lineItems));
}

Answer 2

这应该让你开始：

        string[] lines = placementTwoListBox.Lines;
        for (int line = 0; line < lines.Length; line++)
        {
            string replacement1 = calculatedXRichTextBox.Lines[line];
            while (replacement1.Length < 7)
            {
                replacement1 = " " + replacement1;
            }
            lines[line] = lines[line].Remove(20, 7).Insert(20, replacement1);

            string replacement2 = calculatedYRichTextBox.Lines[line];
            while (replacement2.Length < 7)
            {
                replacement2 = " " + replacement2;
            }
            lines[line] = lines[line].Remove(29, 7).Insert(29, replacement1);
        }
        placementTwoListBox.Lines = lines;

更新：我完全错过了一些列表，而不是所有 RichTextBoxes...查看更新的代码：

    for (int line = 0; line < placementTwoListBox.Items.Count; line++)
    {
        string replacement1 = calculatedXRichTextBox.Lines[line];
        while (replacement1.Length < 7)
        {
            replacement1 = " " + replacement1;
        }
        placementTwoListBox.Items[line] = ((string)placementTwoListBox.Items[line]).Remove(20, 7).Insert(20, replacement1);

        string replacement2 = calculatedYRichTextBox.Lines[line];
        while (replacement2.Length < 7)
        {
            replacement2 = " " + replacement2;
        }
        placementTwoListBox.Items[line] = ((string)placementTwoListBox.Items[line]).Remove(29, 7).Insert(29, replacement1);
    }
