I want to repeat at the end: String is a reference type but since its immutable the line test = "after passing"; actually creates a new object and our copy of the variable test is changed to point to the new string. 回答3 As others have stated, the String type in .NET is immutable...
In .NET, the string type is classified as a reference type. Although string behaves similar to value types in some aspects, such as being immutable and having value-like semantics, it is conceptually treated as a reference type.Value types...

A string is a series of characters, such as "Swift", that forms a collection. Strings in Swift are Unicode correct and locale insensitive, and are designed to be efficient. The String type bridges with the Objective-C class NSString and offers interoperability with C functions that works with...
at()语法: reference at( size_type index ); at()函数返回一个引用,指向在index位置的字符. 如果index不在字符串范围内, at() 将报告"out of range"错误,并抛出out_of_range异常。 1 string str1 = "sagdfa"; 2 string str2 = "iuhkjgsaaaaf"; ...
