C#使用指定的字符替换除首尾字符外的字符串中的字符

方法中也提供了一种由字符数组转换为字符串的方法。

/// <summary>
		/// 使用指定的字符替换除首尾字符外的字符串中的字符
		/// </summary>
		/// <param name="sourceString">原字符串</param>
		/// <param name="ch">指定的字符</param>
		/// <returns></returns>
		private static string ReplaceWithNewStr(string sourceString, char ch)
		{
			char[] tempChar = sourceString.ToCharArray();

			if (tempChar.Length<=2)
			{
				if (tempChar.Length<=1)
				{
					tempChar[0] = ch;
				}
				else
				{
					tempChar[1] = ch;
				}
			}
			else
			{
				for (int i = 1; i < sourceString.Length - 1; i++)
				{
					tempChar[i] = ch;
				}
			}
			
			string str = string.Join("", tempChar);

			return str;
		}
