C# 步进错误处理

我正在运行以下程序：-

    private void ConvertFile()

    {
        PrepElec1();
        MakeElec2();
        MakeElec3();
        MakeElec4();
        MakeElecMerged();
        SetDataSet.SetData(DtSet);
        btnConvert.Enabled = false;
        btnReport.Visible = true;
    }

如何实现try/catch，以便在其中一个失败时

        PrepElec1();
        MakeElec2();
        MakeElec3();
        MakeElec4();
        MakeElecMerged();

---

…我得到一个消息框，显示它在哪个步骤失败？

您可以让异常的堆栈跟踪为您完成这项工作

private void ConvertFile()
{
    try
    {
        PrepElec1();
        MakeElec2();
        MakeElec3();
        MakeElec4();
        MakeElecMerged();
        SetDataSet.SetData(DtSet);
        btnConvert.Enabled = false;
        btnReport.Visible = true;
    }
    catch (Exception e)
    {
        var trace = e.StackTrace;

        // format trace however you like

        MessageBox.Show(this, trace, "Error");
    }
}
