Question

我在测试中使用了一些代码，但它似乎运行良好。现在我正在为游戏开发一个帮助应用程序并试图应用相同的代码，但它失败了。我需要知道是否有一些我忽略的错误。我试图从一个xml文件中读取并在我的winform中填充文本框和组合框。我正确地提取名称，但其余属性不会填充。以下是我的代码示例：

public bool LoadChar(string _filename) //Fetches character stats from xml file and loads to the textboxes
    {
        try
        {
            _name = tbName.Text;//hero                    
            XmlDocument doc = new XmlDocument();//hero                    
            doc.Load(_filename);//hero
            XmlNode _currNode = doc.SelectSingleNode("/Characters/Char[@name='" + _name + "']");//hero                    

            _currNode.Attributes["st"].Value = _st;
            _currNode.Attributes["dx"].Value = _dx;
            _currNode.Attributes["iq"].Value = _iq;
            _currNode.Attributes["ma"].Value = _ma;
            _currNode.Attributes["armor"].Value = _armor;
            _currNode.Attributes["hits"].Value = _hits;
            _currNode.Attributes["wounds"].Value = _wounds;
            _currNode.Attributes["fatigue"].Value = _fatigue;
            _currNode.Attributes["attack"].Value = _attack;
            _currNode.Attributes["dmgdie"].Value = _dmgdie;
            _currNode.Attributes["dmgmod"].Value = _dmgmod;
            _currNode.Attributes["exp"].Value = _exp;
            _currNode.Attributes["description"].Value = _description;
            _currNode.Attributes["equipment_money"].Value = _equipmentmoney;
            _currNode.Attributes["weapons_armor"].Value = _wpnarmor;
            _currNode.Attributes["talents_spells"].Value = _talentspell;
            _currNode.Attributes["gender"].Value = _gender;
            _currNode.Attributes["race"].Value = _race;
            _currNode.Attributes["type"].Value = _type;
            _currNode.Attributes["job"].Value = _job;


            tbName.Text = _name;
            tbSt.Text = _st;
            tbDx.Text = _dx;
            tbIq.Text = _iq;
            tbMa.Text = _ma;
            tbArmor.Text = _armor;
            tbHitStop.Text = _hits;
            tbWounds.Text = _wounds;
            tbFatigue.Text = _fatigue;
            tbAttack.Text = _attack;
            tbDmgDie.Text = _dmgdie;
            tbDmgMod.Text = _dmgmod;
            tbExp.Text = _exp;
            tbDescription.Text = _description;
            tbEquipmentMoney.Text = _equipmentmoney;
            tbWeaponArmor.Text = _wpnarmor;
            tbTalentSpell.Text = _talentspell;
            cbGender.SelectedValue = _gender;
            cbRace.SelectedValue = _race;
            cbType.SelectedValue = _type;
            cbJob.SelectedValue = _job;


            return true;
        }
        catch
        {
            return false;
        }
    }

以下是我尝试从中获取数据的xml文件：

  <?xml version="1.0" encoding="UTF-8" ?> 
- <Characters>
  <Char name="Conan" st="15" dx="13" iq="8" ma="10" armor="Leather" hits="2" wounds="2"     
fatigue="0" attack="Great Sword" dmgdie="3" dmgmod="+2" exp="69" description="Conan is a 
big enthusiastic gentleman" equipment_money="Backpack, 4 gold coins." 
weapons_armor="Great Sword, Longbow." talents_spells="Killing, Maiming, Strangling, 
Boxing, Florist." gender="Male" race="Human" type="Barbarian" job="Unskilled" /> 
  </Characters>

我通过将我的表单中的文本框和组合框写入xml来创建xml文件，但是现在我想从xml加载一个字符，但是在这个例子中它不起作用。我确实让它在另一个例子中工作，我把两者紧密地比较在一起，但除了这个具有更多不同属性的例子之外，找不到任何真正的差异。

注意：我放置了一个断点，_name值拉“柯南”，但所有其他值都为空。

我打算稍后在某些方面对此进行改进 - 现在就把它搞砸了。

您没有从XML加载数据。要读取数据，您需要更改以下位置：

 public bool LoadChar(string _filename) //Fetches character stats from xml file and loads to the textboxes
 {
     try
     {
        _name = tbName.Text;//hero                    
        XmlDocument doc = new XmlDocument();//hero                    
        doc.Load(_filename);//hero
        XmlNode _currNode = doc.SelectSingleNode("/Characters/Char[@name='" + _name + "']");//hero 

        //reading attributes values  
        _st = _currNode.Attributes["st"].Value;
        _dx = _currNode.Attributes["dx"].Value;
        _iq = _currNode.Attributes["iq"].Value;
        _ma = _currNode.Attributes["ma"].Value;
        _armor = _currNode.Attributes["armor"].Value;
        _hits = _currNode.Attributes["hits"].Value;
        _wounds = _currNode.Attributes["wounds"].Value;
        _fatigue = _currNode.Attributes["fatigue"].Value;
        _attack = _currNode.Attributes["attack"].Value;
        _dmgdie = _currNode.Attributes["dmgdie"].Value;
        _dmgmod = _currNode.Attributes["dmgmod"].Value;
        _exp = _currNode.Attributes["exp"].Value;
        _description = _currNode.Attributes["description"].Value;
        _equipmentmoney = _currNode.Attributes["equipment_money"].Value;
        _wpnarmor = _currNode.Attributes["weapons_armor"].Value;
        _talentspell = _currNode.Attributes["talents_spells"].Value;
        _gender = _currNode.Attributes["gender"].Value;
        _race = _currNode.Attributes["race"].Value;
        _type = _currNode.Attributes["type"].Value;
        _job = _currNode.Attributes["job"].Value;


        tbName.Text = _name;
        tbSt.Text = _st;
        tbDx.Text = _dx;
        tbIq.Text = _iq;
        tbMa.Text = _ma;
        tbArmor.Text = _armor;
        tbHitStop.Text = _hits;
        tbWounds.Text = _wounds;
        tbFatigue.Text = _fatigue;
        tbAttack.Text = _attack;
        tbDmgDie.Text = _dmgdie;
        tbDmgMod.Text = _dmgmod;
        tbExp.Text = _exp;
        tbDescription.Text = _description;
        tbEquipmentMoney.Text = _equipmentmoney;
        tbWeaponArmor.Text = _wpnarmor;
        tbTalentSpell.Text = _talentspell;
        cbGender.SelectedValue = _gender;
        cbRace.SelectedValue = _race;
        cbType.SelectedValue = _type;
        cbJob.SelectedValue = _job;


        return true;
    }
    catch
    {
        return false;
    }
}

无法从xml文件读取到文本框和组合框
