这两个中哪个更有效意味着哪个将提供更快的输出第一个

outString =  "My First String";
outString += "My Second String";
outString += "My Third String";
outString += "My Fourth String";
outString += "My Fifth String";
myFinalString = outString;

或者第二个

outString =  "My First String"
+ "My Second String"
+ "My Third String"
+ "My Fourth String"
+ "My Fifth String";
myFinalString = outString;

在其中一个屏幕中,我制作了这样的字符串,它运行超过 100 行,那么您会建议哪一个?
