首先代碼： string myString = "<at>onePossibleName</at> some question here regarding <at>disPossibleName</at>" // some code to handle myString and save it in myEditedString Console.WriteLine(myEditedString); //output now is: some question here regarding <at>disPossibleName</at>我想<at>onePossibleName</at>從 myString 中刪除。該字符串onePossibleName可以disPossbileName是任何其他字符串。到目前為止我正在與string myEditedString = string.Join(" ", myString.Split(' ').Skip(1));這里的問(wèn)題是，如果onePossibleName變成one Possible Name。嘗試也是如此myString.Remove(startIndex, count)- 這不是解決方案。

根據(jù)你想要的，會(huì)有不同的方法，你可以使用 IndexOf 和 SubString，正則表達(dá)式也是一個(gè)解決方案。
// SubString and IndexOf method
// Usefull if you don't care of the word in the at tag, and you want to remove the first at tag
if (myString.Contains("</at>"))
{
var myEditedString = myString.Substring(myString.IndexOf("</at>") + 5);
}
// Regex method
var stringToRemove = "onePossibleName";
var rgx = new Regex($"<at>{stringToRemove}</at>");
var myEditedString = rgx.Replace(myString, string.Empty, 1); // The 1 precise that only the first occurrence will be replaced

string myString = "<at>onePossibleName</at> some question here regarding <at>disPossibleName</at>"
int sFrom = myString.IndexOf("<at>") + "<at>".Length;
int sTo = myString.IndexOf("</at>");
string myEditedString = myString.SubString(sFrom, sFrom - sTo);
Console.WriteLine(myEditedString);
//output now is: some question here regarding <at>disPossibleName</at>

您可以使用這個(gè)通用正則表達(dá)式。
var myString = "<at>onePossibleName</at> some question here regarding <at>disPossibleName</at>";
var rg = new Regex(@"<at>(.*?)<\/at>");
var result = rg.Replace(myString, "").Trim();
這將刪除所有“at”標(biāo)簽及其之間的內(nèi)容。該Trim()調(diào)用是在替換后刪除字符串開頭/結(jié)尾處的所有空格。
