工具類

 

1.跨線程操控窗口UI類

/// <summary> /// 跨線程改變界面UI的工具類 CtrlHelper /// TY /// 20090820 /// </summary> public class CtrlHelper { /// <summary> /// 跨線程改變界面UI /// </summary> /// <param name="ctrl">控制對象</param> /// <param name="c">目標對象</param> /// <param name="prop">目標屬性</param> /// <param name="value">值</param> public static void SetValue(Ctrl ctrl, Control c, string prop, object value) { ctrl.Control = c; ctrl.Property = prop; ctrl.Value = value; SetValue(ctrl); } private static void SetValue(Ctrl c) { if (c.Control.InvokeRequired) { Action<Ctrl> d = new Action<Ctrl>(SetValue); c.Control.Invoke(d, c); return; } c.Control.GetType().GetProperty(c.Property).SetValue(c.Control, c.Value, null); } } /// <summary> /// 控制類 /// </summary> public class Ctrl { private Control _control; private string _property; private object _value; public Control Control { get { return this._control; } set { _control = value; } } public string Property { get { return this._property; } set { _property = value; } } public object Value { get { return this._value; } set { _value = value; } } }

 

2.字符串XML文檔有效字符過濾類

class StringUtil { private static string invalidCharsMatch = "(?ims)[/x0/x1/x2/x3/x4/x5/x6/x7/x8/x9/xb/xc/xe/xf" + "/x10/x11/x12/x13/x14/x15/x16/x17/x18/x19]"; public static string FullHTMLEncode(string rawXml) { return System.Text.RegularExpressions.Regex.Replace(rawXml, invalidCharsMatch, ""); } }

 

3.數字數據處理類

class DataValidateHelper { public static string validateDouble(double value) { if (Double.IsNaN(value) || Double.IsPositiveInfinity(value) || Double.IsNegativeInfinity(value)) { return ""; } else { return value.ToString("f2"); } } public static bool IsNumber(string strNumber) { System.Text.RegularExpressions.Regex r = new System.Text.RegularExpressions.Regex(@"^/d+(/.)?/d*$"); return r.IsMatch(strNumber); } public static string filterDBNull(string date) { return date == null ? "" : date; } }

 

4.Combobox自定義Item結構

public struct ComboxObject { private string key; private string value; public ComboxObject(string key, string value) { this.key = key; this.value = value; } public override string ToString() { return this.value; } public string getValue() { return this.key; } }

 

5.讀取XML文檔參數

class XMLHelper { private XmlDocument xmlDoc; public Hashtable xmlTb = new Hashtable(); private static XMLHelper xmlHelper; private XMLHelper() { try { this.xmlDoc = new XmlDocument(); this.xmlDoc.Load((System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase)) + "//PersonLocation.exe.config"); XmlNodeList nodeList = this.xmlDoc.SelectSingleNode("//appSettings").ChildNodes; foreach (XmlNode xn in nodeList) { XmlElement xe = (XmlElement)xn; if (xe.NodeType == XmlNodeType.Element && xe.LocalName == "add") { xmlTb.Add(xe.GetAttribute("key"), xe.GetAttribute("value")); } } } catch// (Exception e) { //LogHelper.errorLog("Exception : " + e.Message + " detail: " + e.StackTrace); } } public static XMLHelper getInstace() { if (xmlHelper == null) xmlHelper = new XMLHelper(); return xmlHelper; } public void updateXml(string key,string value) { XmlNode xn = this.xmlDoc.SelectSingleNode("//appSettings/add[@key='"+key+"']"); XmlElement xe = (XmlElement)xn; xe.SetAttribute("value", value); this.xmlDoc.Save("PersonLocation.exe.config"); } }
