调用代码：

View Code 
1 info = "";
2 RegistryUtils.CreateSubKey(Constants.REGISTRY_PATH, Constants.VSS_USERNAME, this.txtVssName.Text, out info);
3 if (!info.Equals(""))
4 {
5     MessageBox.Show(string.Format("保存VSS用户名出错，错误信息：{0}", info), "提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
6     return;
7 }
View Code 
1 string info = "";
2 string vssName = RegistryUtils.GetValueByName(Constants.REGISTRY_PATH, Constants.VSS_USERNAME, out info);
