How can update the values of a collection using LINQ in ASP.NET?
We can make use of ForEach extension method which is available as part of LINQ. collection.ToList().ForEach(o => o.PropertyToSet = value); The ToList is needed in order to evaluate the select immediately due to lazy evaluation

How to convert bytes to KB,MB, GB in .NET ?
using Log to solve the problem static String BytesToString(long byteCount) { string[] suf = { "B", "KB", "MB", "GB", "TB", "PB", "EB" }; //Longs run out around EB if (byteCount == 0) return "0" + suf[0]; long bytes = Math.Abs(byteCount); int place = Convert.ToInt32(Math.Floor(Math.Log(bytes, 1024)))Read more
using Log to solve the problem
static String BytesToString(long byteCount)
{
string[] suf = { “B”, “KB”, “MB”, “GB”, “TB”, “PB”, “EB” }; //Longs run out around EB
if (byteCount == 0)
return “0” + suf[0];
long bytes = Math.Abs(byteCount);
int place = Convert.ToInt32(Math.Floor(Math.Log(bytes, 1024)));
double num = Math.Round(bytes / Math.Pow(1024, place), 1);
return (Math.Sign(byteCount) * num).ToString() + suf[place];
}
Another solution
This may not the most efficient way to do it, but it’s easier to read if you are not familiar with log maths, and should be fast enough for most scenarios.
string[] sizes = { “B”, “KB”, “MB”, “GB”, “TB” };
double len = new FileInfo(filename).Length;
int order = 0;
while (len >= 1024 && order < sizes.Length – 1) {
order++;
len = len/1024;
}
// Adjust the format string to your preferences. For example “{0:0.#}{1}” would
// show a single decimal place, and no space.
string result = String.Format(“{0:0.##} {1}”, len, sizes[order]);
