我在FORM1中如何给FORM2的控件赋值?
private void btOK_Click(object sender, EventArgs e)
{



//打开另一个FORM
FrmPurInScan frmPurInScan = new FrmPurInScan();

frmPurInScan.ShowDialog();

//要把数据传到frmPurInScan里面的控件
}

在FrmPurInScan里面写一个方法:
public void setData(string data)
{
.....
}

//打开另一个FORM
FrmPurInScan frmPurInScan = new FrmPurInScan();
frmPurInScan.setData( "xxxx ");
frmPurInScan.ShowDialog();
