下面是个BOOL类型的函数,不知该如何写
private bool JCode(string SID, string str)
{
bool B ;
DataTable Ruledt = dtRule(Comm.Workid, Comm.Proid);
DataTable R_S1 = newdt(SID, Ruledt);
for(int i=0;i<R_S1.Rows.Count;i++)
{
int type = (int)R_S1.Rows[i]["R_type"];
if (type == 1)
{
int S = (int)R_S1.Rows[i]["codeS"];
int E = (int)R_S1.Rows[i]["codeE"];
string Str= (string)R_S1.Rows[i]["Rulestring"];
if(Str!=str.Substring(S-1,E-S+1))
{
B = false;
break;
}
else
{
B=true;
}
}
if (type == 2)
{
int S = (int)R_S1.Rows[i]["Rstart"];
int E = (int)R_S1.Rows[i]["Rend"];
if (S < (Convert.ToInt32(str.Substring(S - 1, E - S + 1))) && (Convert.ToInt32(str.Substring(S - 1, E - S + 1))) > E)
{
B = false;
}
else
{
B = true;
}
}
}
return B;
}
用 foreach 嵌套 if判断 这个应该比较简单
Foreach 实现遍历 在遍历出每一项时 用 if去执行判断就好了
private bool JCode(string SID, string str)
{
bool B ;
DataTable Ruledt = dtRule(Comm.Workid, Comm.Proid);
DataTable R_S1 = newdt(SID, Ruledt);
for(int i=0;i<R_S1.Rows.Count;i++)
{
int type = (int)R_S1.Rows[i]["R_type"];
if (type == 1)
{
int S = (int)R_S1.Rows[i]["codeS"];
int E = (int)R_S1.Rows[i]["codeE"];
string Str= (string)R_S1.Rows[i]["Rulestring"];
if(Str!=str.Substring(S-1,E-S+1))
{
B = false;
break;
}
else
{
B=true;
}
}
if (type == 2)
{
int S = (int)R_S1.Rows[i]["Rstart"];
int E = (int)R_S1.Rows[i]["Rend"];
if (S < (Convert.ToInt32(str.Substring(S - 1, E - S + 1))) && (Convert.ToInt32(str.Substring(S - 1, E - S + 1))) > E)
{
B = false;
}
else
{
B = true;
}
}
}
return B;
}
上面是详细代码!!!
请看我的详细代码
意思是在DT里面遍历,按条件判断,并返回这个判断值(BOOL型)
