Question

我有一些字符串，例如

string word = "This is example text/WS95    1300 G934 100 DAB"

我想删除WS95和G934之间的字符串，因此结果将是： “这是示例文本/ WS95 G934 100 DAB”

有什么办法吗？我尝试使用indexof

int start = word.IndexOf("WS95") + "WS95".length;
int end = word.LastIndexOf("G");

在那之后，我被困住了。

也许有人对此有任何想法吗？

预期结果：“这是示例文本/ WS95 G934 100 DAB”

谢谢

尝试一下。

string word = "This is example text/WS95    1300 G934 100 DAB";
var result = Regex.Replace(word, @"(?<=WS95).*(?= G934)","");

或

string word = "This is example text/WS95    1300 G934 100 DAB";
var match = Regex.Matches(word, @"(.*WS95)(.*1300)(.*)")[0];
var result = match.Groups[1].Value+match.Groups[3].Value;

var key1 = "WS95";
var key2 = "G934";
string word = "This is example text/WS95    1300 G934 100 DAB";
var resultStrings = word.Split(new[] { key1 }, StringSplitOptions.None);
var resultStrings2 = resultStrings[1].Split(new[] { key2 }, StringSplitOptions.None);
var result = resultStrings[0] + key1 +" "+ key2 + resultStrings2[1];

Answer 3

根据给定的字符串。

string name = "This is example text/WS95    1300 G934 100 DAB";

    Console.WriteLine("The entire string is '{0}'", name);

    // remove the contents, identified by finding the `WS95` and `G934` in the string...
    int foundS1 = name.IndexOf("WS95");
    int foundS2 = name.IndexOf("G934", foundS1 + 1);
    if (foundS1 != foundS2 && foundS1 >= 0) {

        name = name.Remove(foundS1 + 4, (foundS2-5) - foundS1);

        Console.WriteLine("After removing '{0}'", name);
    }

尝试

 string word = "This is example text/WS95    1300 G934 100 DAB";
            int start = word.IndexOf("WS95") + "WS95".Length;
            int end = word.IndexOf("1300")+"1300".Length;
            string tmp1 = word.Substring(0, start);
            string tmp2=word.Substring(end);
            string result = tmp1 + tmp2;

Answer 5

如果您的单词始终以空格分隔，并且您希望/不介意删除多余的空格，请采用以下一种方法：

string word = "This is example text/WS95    1300 G934 100 DAB";
string[] array = word.Split(new[] {' '}, StringSplitOptions.RemoveEmptyEntries);
int index1 = Array.IndexOf(array, "text/WS95"); // has to be a whole word between spaces
int index2 = Array.IndexOf(array,"G934");
var result = String.Join(" ",array.Take(index1 + 1).Concat(array.Skip(index2)));
