Question

string projectname= "1.25hr projectA";

如何解析上面的字符串值以删除时间字符串。输入值可以使用格式1hr projectA或1.25hr projectA，输出将为projectA。

projectname = projectname.Substring(0, projectname.IndexOf('r')).Trim();

在这一行中输出像1.25h。

char[] delimiterChars = { 'r' };
string projectname = lstbxindex.SelectedItem.ToString();
string[] words = projectname.Split(delimiterChars);

projectname = projectname.Substring(0, projectname.IndexOf('r')).Trim();

Answer 1

你的问题是模糊的。如果你想删除 /scripts/migrate_ea3_to_ea4等类似的死亡：

"1.25hr "

如果你想修剪并包括最后“hr”

   string source = "my 1.45hr and 5.31hr test project";

   // "my and test project"
   string result = Regex.Replace(source, @"[0-9.]+hr\s+", "");

Answer 2

您可以使用简单的正则表达式解析文本：Regex.Replace(rawValue, @"^[\d|.|hr]+", "").Trim()

[Theory]
[InlineData("1.25hr projectA")]
[InlineData("1hr projectA")]
[InlineData("projectA")]
public void Can_parse_project_name(string rawValue)
{
    var projectName= Regex.Replace(rawValue, @"^[\d|.|hr]+", "").Trim();

    projectName.Should().Be("projectA");
}

拆分字符串直到出现特定字符
