字符串::格式的用途是什么。我也无法通过互联网获得它

Question

void updateList(void) {
    numCam = get_noofcameras_connected();
        if (numCam != 0) {
            CameraSelect->Text = ("Please select Camera");
            CameraSelect->Items->Add("ALL");

            for (int i = 1; i < numCam + 1; i++) {
                CameraSelect->Items->Add(string::format("Camera {0}", i));
            }
        }
        else {
            CameraSelect->Text = ("NO CAMERA CONNECTED");
        }

    }

它给出错误字符串是不明确的。

Answer 1

对于C＃，您可以致电.Format

这里是示例

doc

Decimal pricePerOunce = 17.36m;
String s = String.Format("The current price is {0} per ounce.",
                         pricePerOunce);
Console.WriteLine(s);
