c#如何替換字符串中的部分字符？

string originalString = "This is a \"sample\" string with \"double quotes\".";

    int startPos = 10; // Starting position (inclusive)
    int endPos = 26;   // Ending position (exclusive)
    
    string strFrom = "\"";
    string strTo = "*";

    // Extract the part of the string between startPos and endPos
    string substringToModify = originalString.Substring(startPos, endPos - startPos);

    // Replace double quotes in the extracted substring
    string modifiedSubstring = substringToModify.Replace(strFrom, strTo);

    // Combine the modified substring with the original string
    string resultString = originalString.Substring(0, startPos) + modifiedSubstring + originalString.Substring(endPos);

    Console.WriteLine(resultString);

您可以使用startPos和endPos從替換位置到替換位置進(jìn)行操作。因此。。。strFrom和strTo表示要查找什么圖表（strFrom）并用（strTo）替換它。其他代碼的意思是直截了當(dāng)，但如果你有任何問題，我很樂意回答。
