我得到一个错误标识符 [英] iam getting an error identifier expected

问题描述

DataRow dr = dt.NewRow();
dr["id"] = i;
dr["Name"] = "Name" + i;
dr["Branch"] = Branches[brnc.Next(0, 3)];
dr["Age"] = ag.Next(17, 22);
dr["SocialMarks"] = marks1.Next(50, 100);
dr["MathsMarks"] = marks2.Next(50, 100);
dr["ScienceMarks"] = marks3.Next(50, 100);
dr["TotalMarks"] = dr.["SocialMarks"] +dr.["MathsMarks"] +dr.["ScienceMarks"];
dr["AverageMarks"] =dr.[ "TotalMarks"] / 3.0;

推荐答案

检查拼写：ag应该是年龄吗？

Check your spelling: was "ag" supposed to be "age"?

dr["Age"] = ag.Next(17, 22);

或许：

Perhaps:

dr["Age"] = age.Next(17, 22);

如果那不是'它，双击Visual Studio中的错误消息，它将直接到你不喜欢的行，在该术语下面的红线是抱怨 - 错误很可能是接近，但没有硝酸钾我们只是猜测哪条线。

If that isn't it, double click the error message in Visual Studio, and it will take you directly to the line that it doesn't like, with a red line below the term is it complaining about- the error is likely to be close, but without knowing which line we would just be guessing.
