C#利用反射簡(jiǎn)化給類字段賦值_

1、C#利用反射簡(jiǎn)化給類字段賦值_ 這個(gè)例子主要的思路是建立一個(gè)類和數(shù)據(jù)庫(kù)查詢語(yǔ)句的字段結(jié)構(gòu)是全都的然后利用反射，挺直用數(shù)據(jù)字段名稱進(jìn)行拼湊，給類對(duì)象的字段進(jìn)行賦值 1.類的定義 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 加載字段規(guī)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(字段規(guī)章表沒(méi)有數(shù)據(jù),請(qǐng)馬上聯(lián)系軟件工程師!, MessageBoxIcon.Error); return false; /獲得類信息，為下面的反射調(diào)用做預(yù)備 Type oType = Type.GetType(CCB_Donet.ClassFolder.FieldRuleInfo); /生成類對(duì)象數(shù)組，和數(shù)據(jù)庫(kù)記錄個(gè)數(shù)是全都的 mMainFieldRule = new FieldRuleInf

9、odtGet.Rows.Count; for (int i = 0; i dtGet.Rows.Count; i+) /這里用法反射動(dòng)態(tài)為FieldRuleInfo字段賦值數(shù)據(jù) mMainFieldRulei = new FieldRuleInfo(); for (int j = 0; j dtGet.Columns.Count; j+) /這里挺直獵取類的字段名稱，然后把數(shù)據(jù)庫(kù)里對(duì)應(yīng)字段的值賦值給它 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
