在单选按钮中将bool转换为int

Question

I have never used a Radio Button before. I have a datagridview and I added 3 radio buttons to my form to populate all the data, the is active data and not active data. This is what I am calling for the is active radio button, but it doesn't want to convert the bool to an int.

private void rbIsActive_CheckedChanged(object sender, EventArgs e)
{
    string searchText = txtSearchText.Text;
    //bool sActive = true;
    //int i = sActive ? 1 : 0;
    bool IsActive = Convert.ToInt32(rbIsActive.Checked);
    var listBooks = GetBooks(searchText);
    grdBooks.DataSource = listBooks;
}

What am I doing wrong?

Answer 1

不要转换为int，主要是因为您已将其分配给bool变量。

Answer 2

In this line:

bool IsActive = Convert.ToInt32(rbIsActive.Checked);

you convert a boolean to an int and are trying to save it into a bool variable. This obviously can not work.
