为什么我会得到这个错误？从字符串"Invoice“到类型”Integer“的转换无效

try:
    value = int("Invoice")
except ValueError as e:
    print(f"Error: {e}")

try {
    int value = Integer.parseInt("Invoice");
} catch (NumberFormatException e) {
    System.out.println("Error: " + e.getMessage());
}

let value;
try {
    value = parseInt("Invoice");
    if (isNaN(value)) {
        throw new Error("Invalid conversion");
    }
} catch (e) {
    console.error("Error: " + e.message);
}

try {
    int value = int.Parse("Invoice");
} catch (FormatException e) {
    Console.WriteLine("Error: " + e.Message);
}
