Question

Private Sub TextBox2_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox2.KeyPress
        If e.KeyChar = Chr(13) Then
            If TextBox2.Text.Trim = TextBox1.Text.Trim Then
                Me.Label1.Text = "正确"
            Else
                Me.Label1.Text = "错误"
            End If

    End Sub

Answer 1

用key_down事件来判断
private void txtNewKey_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
string key;
if(e.KeyCode==Keys.Enter)
{
                              if(String.Compare(textBox2.Text,textBox1.Text.Trim())==0&&textBox2.Enabled)
                               {
                              label1.Text="正确";
                                 } } }

Answer 2

private void textBox2_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
if(e.KeyChar=='\r')
{
if(textBox1.Text.Trim()==textBox2.Text.Trim())
{
label1.Text="正确";
}
else
{
label1.Text="错误";;
}
}
}

Answer 3

private void textBox2_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
if(e.KeyChar ==(char)13)
{
if(String.Compare(textBox2.Text,textBox1.Text.Trim())==0&&textBox2.Enabled)
{
label1.Text="正确";
}
else
{
label1.Text="错误";
}
}
}
我试了试运行通过，可以用

Answer 4

e.KeyChar=='\r' 和 e.KeyChar==(char)13 是等价的
