技术要点
1.根据SAPGUI应用程序名动态读取登录配置文件的绝对路径，如果应用程序未安装，则提示相应消息。
2. 根据获取的路径得到配置文件的XML文本字符串,其中包含所有的登录信息，调用上一篇日志解析XML的类方法，得到登录界面结构的文档实例
3.通过文档实例利用控件类动态生成控件的实例TreeView和ListView，作为窗体面板控件的子节点
4.TreeView和ListView联动控制，点击TreeView叶子节点动态加载ListView，点ListView中某一行项目,则根据该项的信息关联配置文件获的的数据信息，动态生成一个*.sap图标文件,并将相关信息构造成结构化字符串写入到*.sap登录文件中，
5.调用SapGui.exe可执行程序打开刚创建好的 *.sap文件，从而实现GUI动态登录；当然这个功能强大的地方不在于此，而是找到了一种不用修改底层数据文件和代码,直接通过前端UI操作来修改底层数据，实现想要的功能的方法

}
break;

break;
}
}
catch
{
return "";

return "";

读取配置文件的类,配置文件是以格式化文本的形式保存，根据其规则动态加载到键值表实例
class AnalyseKeyValueString
{
static Dictionary<string, string>[]source;
static int index = 0;
static Regex regex = newRegex(@"[a-zA-Z0-9-\s]+?=(""(\s|\S)*?""|[^""]*?$)");
static MatchCollection matchCollection;
public static Dictionary<string, string>[]getStruct(string str)
{
string[] keyvalue = new string[2];
string lable = "";
int num = getNum(str);
source = new Dictionary<string, string>[num];
for (int i = 0;i < num; i++)
{
source[i] = new Dictionary<string, string>();
}
string[] lines = str.Split(new char[] { '\r', '\n' },StringSplitOptions.RemoveEmptyEntries);
for (int i = 0;i < lines.Length; i++)
{
if(lines[i][0]=='[')
{
index = 0;
lable = lines[i].Substring(1, lines[i].Length - 2);
continue;
}
matchCollection = regex.Matches(lines[i]);
if(matchCollection.Count == 1)
{
keyvalue =matchCollection[0].Value.Split(newchar[] { '=' }, 2);
source[index].Add(lable, keyvalue[1]);
}
else if(matchCollection.Count > 1)
{
for (int j = 0; j < matchCollection.Count; j++)
{
keyvalue =matchCollection[j].Value.Split(newchar[] { '=' }, 2);
source[index].Add(keyvalue[0].Trim(), keyvalue[1].Replace("\"",""));
}
}
index++;
}
return source;
}
private static int getNum(string str)
{
return new Regex(@"([a-zA-Z0-9-\s]+?=(""(\s|\S)*?""|[^""^\[]*?\r\n)){2,}").Match(str).Value.Split(new char[] { '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries).Length;
}
}解析XML的类AnalyseXML内容有点多，在上一篇日志已经提过，有几个主要的方法
1通过递归的方式将偏平的链表结构转为树状的深度链表结构
private List<tagNest> getNest(List<tagList> ltag)
{
List<tagNest>ntag = new List<tagNest>();
tagNest subtag;
for (int i = 0;i < ltag.Count; i++)
{
subtag = new tagNest();
subtag.tagName = ltag[i].tagName;
subtag.Attribute = ltag[i].Attribute;
subtag.subtag = getNest(Ltag.FindAll(s =>s.parentKey.Equals(ltag[i].Key)));
ntag.Add(subtag);
}
return ntag;
}
public void plain2nest()
{
Ntag = getNest(new List<tagList>() { Ltag[0] });
}2.根据获取的深度链表动态创建TreeView节点
/// <summary>
/// 初始化时用
/// </summary>
/// <paramname="aplicationView"></param>
public void addToAplicationViewTree()
{
getStruct();
plain2nest();
TreeNode node;
TreeNode subNode;
List<tagNest>Nodes = Ntag[0].subtag[1].subtag[1].subtag;
for (int i = 0;i < Nodes.Count; i++)
{
node = aplicationView.treeView1.Nodes.Add(Nodes[i].tagName);
node.SelectedImageIndex = node.ImageIndex = 2; //设置选中后的图片和选中前的一致
for (int j = 0; j < Nodes[i].subtag.Count; j++)
{
Nodes[i].subtag[j].tagName= Nodes[i].subtag[j].Attribute["name"].ToString().Replace("\"","");
subNode = node.Nodes.Add(Nodes[i].subtag[j].tagName);
subNode.SelectedImageIndex = subNode.ImageIndex = 3;
}
}
}
3.根据点击TreeView不同层级的节点响应不同的方法，叶子动态加载ListView
/// <summary>
/// 点击Tree Node时调用
/// </summary>
/// <paramname="aplicationView.listView1">要展示的地方，提前已经创建好了Header</param>
/// <paramname="p">Node节点名称</param>
internal void addToAplicationViewList(TreeNode treeNode)
{
Dictionary<string, string> detail;
if (treeNode.Level == 0)
{
if(treeNode.IsExpanded)
{
treeNode.Collapse();
treeNode.ImageIndex = 2;
treeNode.SelectedImageIndex = 2;
}
else
{
treeNode.Expand();
treeNode.ImageIndex = 1;
treeNode.SelectedImageIndex = 1;
}
}else if (treeNode.Level == 1)
{
aplicationView.listView1.Items.Clear();
tagNestnodes = Ntag[0].subtag[1].subtag[1].subtag.Find(s =>s.tagName.Equals(treeNode.Parent.Text)).subtag.Find(j =>j.tagName.Equals(treeNode.Text));
aplicationView.listView1.BeginUpdate(); //数据更新，UI暂时挂起，直到EndUpdate绘制控件，可以有效避免闪烁并大大提高加载速度
switch(treeNode.Parent.Text)
{
case "Favorites":
aplicationView.nodeStyle = AplicationView.NodeStyle.Favorites;
break;
case "Shortcuts":
aplicationView.nodeStyle = AplicationView.NodeStyle.Shortcuts;
//tagNest nodes =Ntag[0].subtag[1].subtag[1].subtag.Find(s=>s.Attribute.First(q=>q.Value== ""))
aplicationView.listView1.Columns.Clear();
aplicationView.listView1.Columns.Add("名称", 120, HorizontalAlignment.Left);

for (int i = 0; i < nodes.subtag.Count; i++)
{
nodes.subtag[i].tagName = nodes.subtag[i].Attribute["name"].ToString().Replace("\"", "");
ListViewItem lvi = new ListViewItem();
lvi.ImageIndex = 4; //通过与imageList绑定，显示imageList中第i项图标
lvi.Text =nodes.subtag[i].tagName;
detail =aplicationView.listViewDetailShortcuts.First((s) => s["Label"] == lvi.Text);

aplicationView.listView1.Items.Add(lvi);
}
break;
case "Connections":
