C#利用反射简化给类字段赋值_

1、C#利用反射简化给类字段赋值_ 这个例子主要的思路是建立一个类和数据库查询语句的字段结构是全都的然后利用反射，挺直用数据字段名称进行拼凑，给类对象的字段进行赋值 1.类的定义 namespace CCB_Donet.ClassFolder public class FieldRuleInfo public string gStrFNo; public string gStrFName; public string gStrFLock; public string gStrFCaption; public string gStrFType; public string gStrFMust; pu

2、blic string gStrFMin; public string gStrFMax; public string gStrFDefault; public string gStrFDate; public string gStrFDB; public string gStrFAllow; public string gStrFDisallow; public string gStrFSB; public string gStrFBig; public string gStrFSmall; public string gStrFInputMethod; public string gStr

3、FCHK; public string gStrFRelation; public string gStrFDesc; public string gStrFSecond; public string gStrFQC; public string gStrFException; public string gStrFASupp; public string gStrFYQH; public string gStrFPos; public string gStrFStar; public string gStrFSave; public string gStrFAddress; public s

4、tring gStrFLblColor; public string gStrFIsCheckList; #region 加载字段规章 private bool m_GetRule() string strSQL = ; DataTable dtGet = null; #if(DEBUG) try #endif if (Common.gIntTypeOrder = 95) strSQL = select A.FNo,A.FName,A.FLock,A.FCaption,A.FType, + A.FMust,A.FMin,A.FMax,A.FDefault,A.FDate,rn + A.FDB,

5、A.FAllow,A.FDisallow,A.FSB,A.FBig,A.FSmall,A.FInputMethod, + A.FCHK,A.FRelation,A.FDesc,A.FSecond,rn + A.FQC,A.FException,A.FASupp,A.FYQH,A.FPos,A.FStar,A.FSave,+ A.FAddress,A.FLblColor,A.FIsCheckList from P_Field_Rule95 A rn + INNER JOIN P_Field_Initial B ON A.FNo=B.FNo rn + where A.FormType=1 AND

6、B.FSection=1 AND + (B.FRegion95=1 OR B.FRegion95=-1) ORDER BY A.FOrder; else strSQL = select A.FNo,A.FName,A.FLock,A.FCaption,A.FType,+ A.FMust,A.FMin,A.FMax,A.FDefault,A.FDate,rn + A.FDB,A.FAllow,A.FDisallow,A.FSB,A.FBig,A.FSmall,+ A.FInputMethod,A.FCHK,A.FRelation,A.FDesc,A.FSecond,rn + A.FQC,A.FE

7、xception,A.FASupp,A.FYQH,A.FPos,A.FStar,+ A.FSave,A.FAddress,A.FLblColor,A.FIsCheckList + from P_Field_Rule A rn + INNER JOIN P_Field_Initial B ON A.FNo=B.FNo rn + where A.FormType= + Common.gIntFormType.ToString() + AND B.FSection=1 AND (B.FRegion= + Common.gIntRegion.ToString() + OR B.FRegion=-1)

8、ORDER BY A.FOrder; dtGet = DB.GetDataTableBySQL(strSQL); if (dtGet.Rows.Count = 0) Common.ShowMessage(字段规章表没有数据,请马上联系软件工程师!, MessageBoxIcon.Error); return false; /获得类信息，为下面的反射调用做预备 Type oType = Type.GetType(CCB_Donet.ClassFolder.FieldRuleInfo); /生成类对象数组，和数据库记录个数是全都的 mMainFieldRule = new FieldRuleInf

9、odtGet.Rows.Count; for (int i = 0; i dtGet.Rows.Count; i+) /这里用法反射动态为FieldRuleInfo字段赋值数据 mMainFieldRulei = new FieldRuleInfo(); for (int j = 0; j dtGet.Columns.Count; j+) /这里挺直猎取类的字段名称，然后把数据库里对应字段的值赋值给它 FieldInfo fieldInfo = oType.GetField(gStr + dtGet.Columnsj.ColumnName, BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Static); fieldInfo.SetValue(mMainFieldRulei, dtGet.Rowsij.ToString(); return true; #if(DEBUG) catch
