将文本框数据转换为整数

Question

我正在尝试在文本框中输入值，并且我想转换为整数。我正在使用 VBA 2013。

我尝试了多种方式，但我一直都在期待

Rated_current = CInt(Int(TextBox_RatedCurrent.Text))

Rated_current = CInt(TextBox_RatedCurrent.Text)

Rated_current = Convert.toInt32(TextBox_RatedCurrent.Text)

Private Sub TextBox_Bmax_TextChanged(sender As Object, e As EventArgs) Handles TextBox_Bmax.TextChanged

    Rated_current = CInt(Int(TextBox_RatedCurrent.Text))
    Mod_current = TextBox_RatedCurrent.Text * TextBox_TotalDrate.Text
    Calculated_TempRise.Text = CInt(Max_temp / ((Log10(Mod_current) / Log10(Rated_current)) * 1.64))
End Sub

Answer 1

在 V2013 c# 中试试这个

int Rated_current;
bool check = int.tryParse(TextBox_RatedCurrent.Text,out Rated_current);
if(!check)
{

//Incoming value is wrong

}
