我想知道如何将2个价格作为数据类型字符串进行比较.

例;

string oldPrice = "£1.99";
string newPrice = "£2.50";

我想比较newPrice是> = oldPrice但我不确定如何将字符串转换为decimal/int.脱掉£符号.

有任何想法吗？关于如何解决这个问题的提示或技巧？

我正在尝试在表中加载时对列进行密码字符化。

下面的代码加载表。

//Fills out Student table
private void loadStudentTable()
{
    SqlConnection conn2 = new SqlConnection(@"Data Source=(LocalDB)\v11.0; AttachDbFilename=C:\Users\Donald\Documents\Visual Studio 2013\Projects\DesktopApplication\DesktopApplication\Student_CB.mdf ;Integrated Security=True");
    conn2.Open();

    try
    {
        SqlCommand cmdDatabase2 = new SqlCommand("Select * from Student", conn2);
        SqlDataAdapter sda2 = new SqlDataAdapter();
        sda2.SelectCommand = cmdDatabase2;
        DataTable dbdataset2 = new DataTable();
        sda2.Fill(dbdataset2);
        BindingSource bSource2 = new BindingSource();
        bSource2.DataSource = dbdataset2;
        studentGridView.DataSource = bSource2;
        sda2.Update(dbdataset2);
        studentGridView.Columns[0].Width = 92;
        studentGridView.Columns[1].Width = 200;
        studentGridView.Columns[2].Width = 180;
        studentGridView.Columns[3].Width = 180;
        studentGridView.Columns[4].Width = 170;
        studentGridView.Columns[5].Width = 170;
        studentGridView.Columns[6].Width = 130; …

我的CSS导航栏出现问题.我无法删除导航栏中的结束行.它看起来不合适而且不专业.

当我减去宽度时,它只是移动导航栏下方的结束选项卡.

有关如何解决此问题的任何帮助或想法？
