heres the error Argument 2: cannot convert from 'method group' to 'float'
heres the code
public Transform[] Spawns;
Random.Range(1, Spawns.GetLength);


Array.GetLength is the name of a method, meaning you need to supply a list of arguments enclosed in () to invoke it:
Random.Range(1, Spawns.GetLength(0));
That being said, the more idiomatic solution for assessing the length of a 1-deminsional array in C# would be to just use the Length property:
Random.Range(1, Spawns.Length);

when I try to use TryParse I get error CS0029, pls see below:
static void Main(string[] args)
{
double m1,m2,m3,m4,m5,m6,m7,m8,m9,m10,m11,m12;
double notval = 0;
Console.WriteLine("Please insert the rainfall in January:");
m1 = double.TryParse(Console.ReadLine(), out notval) ;
I get the error "Cannot implicitly convert type 'bool' to 'double'" (CS0029).

TryParse returns of it was successful at parsing or not, and puts the result (if successful) in the out parameter (on you case notval).. so use:
if(double.TryParse(Console.ReadLine(), out notval))
{
// Do what you want with notval
}

private int skor 0;
it says "syntax error "," expected" and i cant figure out why i am very new at unity sorry if it has a very obvious answer.

You are missing assignment operator = in your skor declaration:
private int skor = 0;

The left-hand side of an assignment must be a variable property or indexer - property can't be set [closed]

SML is a property of regelSML. I want to set regelSML to a value given by Reader.getString(i).
if(reader.GetName(i) = "SML") regelSML.SML = reader.GetString(i);

As clarification, like Guy wrote in the comments above, you are not doing a comparison in the condition.
A single = is for assignments.
You need the comparison-operator ==.

What kind of identifier does the visual studio needs ? i just want to put from outside one int array with 2 different numbers between 0 and 66.
public static void playerLocationChange(int[])
{
}

You have to give the parameter a name. Otherwise, you have no way of referring to it from the function.
public static void playerLocationChange(int[] myIntArrayParam)
//Notice the name next to int[]
//This is the parameter's name
{
}

Well, I need to subtract the number from a string, and in the end she should continue being a string ...
I try:
PStruct.character[Index, PStruct.player[Index].SelectedChar].Y =
(Convert.ToInt32(PStruct.character[Index, PStruct.player[Index].SelectedChar].Y) - 1)
.ToString;
Character.Y is a string.
The error:
Cannot convert method group "ToString" to non-delegate type "string".
Anyone have tips or a solution?

Use parenthesis to invoke/call a method:
expr.ToString()
Without parenthesis it (ToString) is treated as a "method group", which is useful in some cases - but not here.

As written, you are trying to treat a function ToString as a type string.
As the comment mentioned, you probably meant to write ToString().
