inline variables

When using Int.tryparst, declare the variable first for the out parameter

int D;

Int.tryparse (S,out D);

The use of inline variable notation can be as follows. Functionality simplifies writing

Int.tryparse (s,out int d)

$ "{Val1}-{val2}"

Functions like String.Format ("{0}-{1}", Val1,val2), which is parsed as a variable within {} in the string that begins with $.

Method of writing in the method

You can write some methods inside the method. js-like this write a function in the function

function ShowMsg (msg)

{

function validate () {}

}

/*

For example, the processing of a numeric string sort, if it is only a temporary use, you can not add a method, directly in the method to write a processing method on the line.

*/

Sort a number into a string

private string OrderList (String strnum)

{

}

Given string, returns the sorted result

public string Orderstringnum (String Str,int ordertype)

{

return this.orderlist (str);

}

Write directly within the method

Given string, returns the sorted result

public string Orderstringnum (String Str,int ordertype)

{

String OrderList (String strnum)

{

}

return orderlist (str);

}

Note: The method cannot be preceded by the private public, and it can only be used inside a declarative method. Similar to lambda, but it is essentially a method, and it is not as awkward to write as lambda.
