如何从 TextBox 获取值并自动应用格式? [英] How to get values from a TextBox and apply a format automatically?

问题描述

下面是我的占位符，其中的值是硬编码的:

Below is my place holder in which the values are hard-coded:

var abc = string.Format($"{123456} {123456} {12345} {123456789012345} {12345678901234567890123} {1234} {1234} {123} {1234567890123} {123456789012345} {1} {123456789012345} 
{123} {12} {12345678901234567890} {1} {1234}");

File.WriteAllText(
    FilePath + "\\CDR-" + 
    DateTime.Now.ToString("MM-dd-yyyy HH-mm-ss") + ".txt", abc);

但我想在这些占位符中自动从 TextBox 获取值.

But I want to get values from the TextBox automatically in these placeholders.

假设下面是我的 TextBox 及其值:

Suppose below is my TextBox and its value:

123456 123456 12345 123456789012345 12345678901234567890123 
1234 1234 123 1234567890123 123456789012345 1 123456789012345 
123 12 12345678901234567890 1 1234

推荐答案

可以使用序列分隔符来分割输入字符串(这里好像是一个空格)，使用string.Spilt() 作为 字符串的输入.Format() 方法.

You can split the input string using the sequence separator (it appears to be a white space here), and use the string array generated by string.Spilt() as the input of the string.Format() method.

像这样:

string filePath = @"[Some Path]";
string[] values = textBox1.Text.Split();
var format = string.Format(
    "{0} {1} {2} {3} {4} {5} {6} {7} {8} {9} {10} {11} {12} {13} {14} {15} {16}",
    values);

File.WriteAllText(Path.Combine(filePath, 
    "CDR-" + DateTime.Now.ToString("MM-dd-yyyy HH-mm-ss") + ".txt"), 
    format);

如果您有不同的分隔符，请将其指定为 Split() 方法的参数.

If you have a different separator, specify it as a parameter of the Split() method.

空格是预定义的字符.在这种情况下不需要指定它.使用不同的符号:

The white space is the predefined character. No need to specify it in this case. With different symbols:

• 单个字符:[someString].Split(',');
• 不止一个:[someString].Split(new[] {',', '+'});
• 字符串:[someString].Split(new[] { ",", "+" }, StringSplitOptions.RemoveEmptyEntries);
