[在几乎所有我使用'私人'或'公共'的情况下，我都会收到此错误。我最近将班级从[...]更改为get; set;

public string Title
{
    get { return title; }
    set { title = value; }

}
到...

public static string Title
{
    get;
    set;
}
有错误显示在...

private void cBxEmployment_SelectedIndexChanged_1(object sender, EventArgs e)
{
    //sets the job list combo box to visible if "Employed" or "Self Employed" is selected by user, if not selected jobs list combo box is not visible.
    if (cBxEmployment.SelectedIndex == 0 || cBxEmployment.SelectedIndex == 1)
    {
        lblJob.Visible = true;
        cBxJob.Visible = true;
    }
    else
    {
        lblJob.Visible = false;
        cBxJob.Visible = false;
    }
}

private void btnExit_Click(object sender, EventArgs e)
{
    //when exit button is clicked user will get a message box asking if they want to exit, if yes program closes
    DialogResult answer = MessageBox.Show("Would you like to exit?", "Exit", MessageBoxButtons.YesNo);
    if (answer == DialogResult.Yes)
    {
        //close program
        Application.Exit();
    }
}

private void btnClear_Click(object sender, EventArgs e)
{
    cBxTitle.SelectedIndex = -1;
    txtFName.Text = "";
    txtLastname.Text = "";
    txtDOB.ResetText();
    cBxEmployment.SelectedIndex = -1;
    cBxJob.SelectedIndex = -1;

    cBxRelationship.SelectedIndex = -1;

    cBxTitle.Focus();
依此类推...

即使我将其从公共更改为私人，反之亦然，它仍然会引发此错误。

Answer 1

您有一个嵌套函数，在C＃中，这些称为局部函数，没有作用域。因此，您需要删除访问修饰符。

Answer 2

您也将示例中的属性更改为static：public static string Title
