从第1行标题中查找列，并获取列号（Excel.interop？

Question

If I have an excelsheet like

Name, age, ID;

Peter, 35, 123456;

Is there a way for me to locate that age is column numner 2, by searching for age in row 1, or similar?

Answer 1

What you can do is iterate through every column in the excel sheet and create a dictionary for every name/value pair. For example, 0 would map to Name, 1 would map to age and 2 would map to ID. From here, you may iterate through each row and for each column in that row look-up the name value pair (based on column ID). From there, you'll be able to determine the age.

Yes. Assuming the rows are really kept in the format you specified, separated by a comma, you can easily use string's Split method, and Linq's Select method:

        string row = "Name, age, ID";
        int columnNum = Array.IndexOf(row.Split(',')
                                .Select(x => x.Trim()).ToArray(), "age") + 1;

Explanation:

row.Split(',') - this method splits the string into an Array of strings: { "Name", "age", "ID" }

.Select(x => x.Trim()).ToArray() - this expression use LINQ to eliminate all the unnecessary spaces in the column Name (the method Trim() removes spaces at the beginning and at the end of the string).

Array.IndexOf - This method finds the index of the desired value ("age") within the array.

Indexes in C# begins at zero. namely, the index of "Name" is 0, and the index of "age" is actually 1 (and so on). To solve this I simply add 1 to the number returned by "IndexOf".

I'm warmly recommend to read any C# basic tutorial. it's all there :)
