Question

I am trying to parse the string and see if the value after “:” is Integer. If it is not integer then remove “Test:M” from string.

Here is the example string I have.

string testString = "Test:34,Test:M";

The result I need testString = "Test:34"

string[] data = testString.Split(',');
for (int i = 0; i < data.Length; i++)
{
    string[] data1 = data[i].Split(':');
    int num = 0;
    if(Int32.TryParse(data1[1], out num))
    {

    }
}

You could continue on with the looping structure but I, personally, like the look of LINQ a little better:

var dummy = 0;

var intStrings =
    testString.Split(',')
        .Where(s => s.Contains(":") && int.TryParse(s.Split(':')[1], out dummy))
        .ToArray();

var result = String.Join(",", intStrings);
