Hi i want a help infact clarification of a doubt. I want to know how to read values into a jagged array through keyboard just like we enter values in arrays. Everywher its mentioning only initialization ,i.e feeding the values through code itself. I want to get values from user. How would the coding be? Please help me.
class Program
{
static void Main(string[] args)
{
string[][] stringarr1 = new string[15][];
for (int i=0;i<stringarr1.Length;i++)
{
stringarr1[i]=Console.ReadLine();
}
for(int j=0;j<stringarr1.Length;j++)
{
Console.WriteLine(stringarr1[j]);
}
}
}

This is the code i wrote to read and display strings. But it shows error in the bold statement.

Hoping to receive immediate reply.
Thank you!!!

@Sina

Hi,

Hope this helps you

Console.Write("Enter no of rows : ");
int iNoOfRows = Convert.ToInt32(Console.ReadLine());
string[][] stringarr1 = new string[iNoOfRows][];
Console.WriteLine("\n");
for (int i = 0; i < stringarr1.Length; i++)
{
Console.Write("No of columns for row " + (i + 1) + " : ");
stringarr1[i] = new string[Convert.ToInt32(Console.ReadLine())];
}
Console.WriteLine("\n");
for (int i = 0; i < stringarr1.Length; i++)
{
for (int j = 0; j < stringarr1[i].Length; j++)
{
Console.Write("Enter value for Row " + (i + 1) + ",Column " + (j + 1) + " : ");
stringarr1[i][j] = Console.ReadLine();
}
Console.WriteLine();
}

Console.WriteLine("Reading values..\n");

for (int i = 0; i < stringarr1.Length; i++)
{
for (int j = 0; j < stringarr1[i].Length; j++)
{
Console.Write(stringarr1[i][j].ToString() + "\t\t");

}
Console.WriteLine();
}

Console.WriteLine("\n\nPress any key to continue........");
