这一段C#代码谁帮我分析一下是什么意思

Question

      public void Clear_Table(Control.ControlCollection GBox, string TName)
        {
            string sID = "";
            foreach (Control C in GBox)//这一句是什么意思啊
            {
                if (C.GetType().Name == "CheckBox")//C怎么出来的它代表什么
                {
                    sID = C.Name;
                    if (sID.IndexOf(TName) > -1)
                    {
                        if (((CheckBox)C).Checked == true)
                        {
                            string TableName = "";
                            string[] Astr = sID.Split(Convert.ToChar('_'));
                            TableName = "tb_" + Astr[1];
                            if (Astr[1].ToUpper() == ("Clew").ToUpper())
                            {
                                MyDataClass.getsqlcom("update " + TableName + " set Fate=0,Unlock=0 where ID>0");

Answer 1

public void Clear_Table(Control.ControlCollection GBox, string TName)
        {
            string sID = "";
            foreach (Control C in GBox)//遍历GBox集合里面的每一个控件
            {
                if (C.GetType().Name == "CheckBox")//当前遍历到的控件 
                {
                    sID = C.Name;
                    if (sID.IndexOf(TName) > -1)
                    {
                        if (((CheckBox)C).Checked == true)
                        {
                            string TableName = "";
                            string[] Astr = sID.Split(Convert.ToChar('_'));
                            TableName = "tb_" + Astr[1];

Answer 2

谁能更清楚的帮我析一下吗
比如if (sID.IndexOf(TName) > -1)
这句是什么意思啊
还有这个else
                            {
                                MyDataClass.getsqlcom("Delete " + TableName);
                                if (Astr[1].ToUpper() == ("Login").ToUpper())
                                {
                                    MyDataClass.getsqlcom("Delete tb_UserPope");
                                    MyDataClass.getsqlcom("insert into " + TableName + " (ID,Name,Pass) values('0001','TSoft','111')");
                                    ADD_Pope("0001", 1);
                                }
                            }

Answer 3

public void Clear_Table(Control.ControlCollection GBox, string TName)
        {
            string sID = "";
            foreach (Control C in GBox)//遍历GBox集合里面的每一个控件
            {
                if (C.GetType().Name == "CheckBox")//当前遍历到的控件 如果是checkbox类型的话
                {
                    sID = C.Name;
                    if (sID.IndexOf(TName) > -1）匹配(比较)Tname和c.name，不相等返回-1,
                    {
                        if (((CheckBox)C).Checked == true)
                        {
                            string TableName = "";
                            string[] Astr = sID.Split(Convert.ToChar('_'));将c.name按_分开，并放在数组中，例如ca_hh_aa就分为
                                                                                      Astr[0]=ca,Astr[1]=hh,Astr[2]=aa
                            TableName = "tb_" + Astr[1];//tableName的值为tb_加上c.name的_后的字符。
                            if (Astr[1].ToUpper() == ("Clew").ToUpper())//若c.name的_后的字符为clew,将表中数据都置0
                            {
                                MyDataClass.getsqlcom("update " + TableName + " set Fate=0,Unlock=0 where ID>0");
                            }
                            else
                            {
                                MyDataClass.getsqlcom("Delete " + TableName);
                                if (Astr[1].ToUpper() == ("Login").ToUpper())//若
                                {
                                    MyDataClass.getsqlcom("Delete tb_UserPope");
                                    MyDataClass.getsqlcom("insert into " + TableName + " (ID,Name,Pass) values('0001','TSoft','111')");
                                    ADD_Pope("0001", 1);
                                }
                            }
                        }
                    }
                }
            }
        }

Answer 4

兄弟，if 里面返回的bool类型的值（ture/false）,怎么会返回-1呢？
那几代码调用了IndexOf()方法进行比较

Answer 5

    foreach (Control C in GBox)//这一句是什么意思啊
GBOX中的每一个控件c
 if (C.GetType().Name == "CheckBox")//C怎么出来的它代表什么 
if(c.类型名=="CheckBox")
sID.IndexOf(TName) > -1
sId名称包含TName

            string sID = "";

                            TableName = "tb_" + Astr[1];                     //给变量赋值如：tb_tb1  
                            if (Astr[1].ToUpper() == ("Clew").ToUpper())    //如果分解的SID(控件编号ID）的‘-’后部分等于'clew' 最好用eqals方法
                            { 
                                MyDataClass.getsqlcom("update " + TableName + " set Fate=0,Unlock=0 where ID>0"); 　//将所有的表两个字段更新为0(sql语　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　//句返回）
