Invoke(delegateMethod)参数计数不匹配

原

private void WriteLabel(string s)
        {
            if (label1.InvokeRequired)
            {
                WriteLabelDeletegate d = new WriteLabelDeletegate(WriteLabel);
                label1.Invoke(d);
            }
            else
            {
                label1.Text = s;
            }
        }

报错:参数计数不匹配

改后

private void WriteLabel(string s)
        {
            if (label1.InvokeRequired)
            {
                WriteLabelDeletegate d = new WriteLabelDeletegate(WriteLabel);
                label1.Invoke(d, new object[] { s });
            }
            else
            {
                label1.Text = s;
            }
        }
